This is the set of steps we did to migrate our GroupWise from NetWare to OES2 Linux, in conjunction with an ID transfer. It is not the only method to migrate GroupWise. Please note that our setup we used a DEDICATED volume of: GW to house the domain and post offices. We did not have other file services on that volume (ie, we did not mix user data with the GroupWise data). This only covers MTA/POA migrations. You may also wish to refer to Danita Zanre's migration/move guides at http://www.caledonia.net
This document may be broken into two sections: Standalone server and Cluster servers. The reason for this is that a cluster server does not require that the NSS Volume be migrated from NetWare to another Linux server. Rather, NCS migrations can simply mount the existing NSS Volume.
First, you will need to adjust some disk settings (if you have not already done so).
Edit the /etc/fstab file (you can use vi or gedit)
Find the line where it mounts the GW volume and add the word: noatime before the 0,0 like shown below:
This assumes the OES2 Linux server is up and running and has not had an ID transfer done yet.
Click OK
Click Install Products
Click GroupWise Agents
Click Install Agents
Click OK
Click the back button (we will configure later)
Then click the Exit button
In the same terminal window, cd into the /admin directory
You'll see 4 RPM files there. (The versions may be different if you are using 8.0.1 HP1 codebase).
We need to install two of them.
First, install the dbcopy by typing:
rpm –Uvh novell-groupwise-dbcopy-8.0.1-88138.i586.rpm
We'll install the gwcheck later.
Type: mkdir /mnt/gw1
Make sure to do this while you're doing the initial data transfer. You can safely do this during the day while the system is up and running
Now type:
ncpmount –S server –A IP –U userid –P password /mnt/gw1
Where server = name of source netware server
Where IP = IP of the source NetWare server
Where userid = your userid in FQDN format like: .jsmith.nyc.us.abc
Where password = your password
Example:
ncpmount –S nwserver-1 –A 192.168.10.1 –U .jsmith.nyc.us.abc –P password /mnt/gw1
Now type:
cd /opt/novell/groupwise/agents/bin
Now type:
./dbcopy –m –p –f /mnt/gw1/GW/podirectory /media/nss/GW/podirectory
Where podirectory is the name of the post office directory.
Example:
./dbcopy –m –p –f /mnt/gw1/GW/po2 /media/nss/GW/po2
There's space in front of the /mnt and /media words.
Don't forget the –m –p –f switches or bad things will happen and you'll waste a lot of time.
Make sure you do this while you're doing the final data copy with the MigGUI. Make sure to do this BEFORE the ID TRANSFER, but AFTER the "shutdown time" (ie, you want to do this final copy after you shutdown the groupwise agents on the final day).
On the day of the final Data Transfer:
We're going to do two passes with dbcopy. A final one for the Domain (we did not do an initial pass before), and a second one for the final pass of the PO.
Domain first:
(this also assumes that you have an ncpmount to the Source NetWare server)
./dbcopy –m –d /mnt/gw1/GW/domain /media/nss/GW/domain
For example:
./dbcopy –m –d /mnt/gw1/GW/domain1 /media/nss/GW/domain1
The copy should go very quickly as we don't have hardly anything in our domain directories.
Post Office:
./dbcopy –m –p –s /mnt/gw1/GW/po2 /media/nss/GW/po2
That's it. You should be all done with the Data Transfer.
Now that you have your data, we need to verify a few things. You can do this before the ID Transfer.
At a terminal
cd /media/nss/GW/gw80sp1
Then type:
./install
Click OK
Click Install Products.
Click GroupWise Agents
Click Configure Agents
Click Next
Accept the terms and click Next
Click Add
Keep everything lower case. The Exception is that the volume name CAN be upper case (and it will always be upper case). Use the browse button to avoid typos.
Click OK
Do this for each agent that's on the server (in the case of TEST01, I have one domain and two PO to configure)
Click OK
Click OK
Now click Next
Make sure to have the "launch agents on system startup" checked (it is by default) and then click Exit. This actually creates the necessary startup files for Linux to start GroupWise as a daemon.
You may need to edit the startup files for the MTA for any custom switches/settings you had on NetWare. In our case, we need to edit the startup files for the MTA to increase the # of tcpinbound connections.
cd /opt/novell/groupwise/agents/share
You'll see the .mta and .poa startup files
Edit the .mta file (you can use vi or gedit)
Make sure you have the line:
--tcpinbound 80
in the file. Then save it.
cd to the:
/opt/novell/groupwise/agents/bin directory
Use the following syntax:
./gwpoa -show -home /path -noconfig
That's TWO dashes in front of show, home, and noconfig
For this example:
./gwpoa -show -home /media/nss/GW/training/testpo –noconfig
If things are okay, you should see this:
Do not load more than one agent at a time in this state (we loaded it with NO configuration).
This is ONLY to verify functionality at this point. We still have more work to do.
Exit the groupwise client and then exit the PO by clicking File -> Exit
Very that the MTA loads by using:
./gwmta -show -home /path
Where /path = the path of the domain (ie: /media/nss/GW/traindom)
File -> Exit
Now we have to use ConsoleOne to adjust everything (the paths and things)
This next part you have to do AFTER the ID Transfer.
Fire up ConsoleOne (I'm assuming Windows workstation here, vs. on the Linux server itself) from the laptop:
Right-click the domain object of the server you migrated and select Properties
Use the browse button to select the path so that it shows lower case. Technically this part here is just used by ConsoleOne.
Do the same for the Post Office (NOT the POA):
Again, browse the path.
More importantly is on the MTA and POA objects.
Click the View in ConsoleOne to look at MTA and find the MTA for the domain you migrated and click properties for it.
For the platform select Linux
Click GroupWise -> Log Settings
Change the path to be relative and with the slashes being the other direction. For example, the above setting would be:
/media/nss/GW/training/traindom/logs
Do the same for the Message Logging section underneath GroupWise tab.
For the POA, make sure you select the PO first in ConsoleOne (the one that you migrated) and THEN access the POA (if you don't, you won't be able to change the platform):
Again, change to Linux.
Then under GroupWise tab, change the Log Settings:
After you change these settings, we'll load the agents once more.
From a terminal type:
cd /opt/novell/groupwise/agents/bin
then type:
./gwmta -show @traindom.mta
Make sure it launches, wait a few minute and make sure it has domains that are open. You can keep it up and running for the time being.
Functional MTA screen:
If all goes well, then you will need to rebuild the Post Office via ConsoleOne for the database to take the new changes you made in page 26.
Using ConsoleOne, right-click the Domain you migrated and select: Connect
I will use the TEST site migration as an example:
Note I have a little "connector" icon next to REG40
Now, right-click the PO object and select GroupWise Utilities -> System Maintenance
Select Rebuild Database and click Run
Normally to ensure that things are rebuilt, I will rebuild to a temp directory like: c:\temp
Then click OK
If you're doing this locally it should be quick. About 2 minutes. If not, it can take a while.
There's about 11,000 records or so. (obviously this depends upon your system. I would not recommend doing this across a WAN link as it will take forever in a large system).
When it's done:
Click OK.
Then click Close.
At this point, I map a drive to the OES2 server's GW volume.
RENAME the wphost.db file in the post office directory (again, example of TEST):
\GW\po1\wphost.db
Rename it to .old
Then CUT and PASTE the one from your c:\temp directory to that directory on the OES2 server.
Once you have rebuilt the post office databases, you can now try to load them.
Open yet another Terminal and cd into the /opt/novell/groupwise/agents/bin directory and type:
./gwpoa –show @testpo.poa
Wait for it to load. If all is well it will stay loaded. Verify connectivity with a client PC.
Functional POA screen:
(Ignore the fact that it shows GroupWise 7.0.3 That's just an admin field we forgot to change).
Now exit all the agents.
Lastly, there's a bug and so I suggest ALWAYS doing this:
Open a terminal and type:
chkconfig grpwise off
chkconfig grpwise on
Lastly, unload (File -> Exit) both the MTA and POA.
Once they're unloaded type this from a terminal to verify they load once more:
rcgrpwise start
You will NOT see an agent window. To verify they are running:
rcgrpwise status
You want to see green items saying running (of if not using Putty you want to see the word: running)
Then type:
rcgrpwise stop
Edit the post office startup file (ie: po1.poa) Go to the end of the file and add a line that says simply:
--nodca
That's a "dash" "dash" nodca
(this turns off the document conversion agent).
Reboot the server (you can do this when you do the final reboot to verify DHCP and iPrint and all that) and you should be able to connect to groupwise.
Biggest change will be that you CANNOT have the agents auto-start AND get a GUI screen for the agents like what is shown above. You will have to use the GroupWise HTTP interface if you wish to look at the agent status.
To adjust the NDS Synchronization, do this:
Launch ConsoleOne -> GroupWise System Operations -> eDir User Synchronization
Find the Domain that you just migrated and click Configure Agents
Now, scroll through the list to find the MTA of the domain you just migrated and click Set Up eDirectory Access.
In our case, we have two LDAP servers already defined in GroupWise.
Click the Set Preferred button so that LDAP1 is the "preferred" server. (Change this for your own environment).
Click the browse icon button for the LDAP user name. This is the userid that you want the MTA to login to eDirectory (via LDAP) to do the sync. I would suggest creating a dedicated LDAP account for this purpose for auditing and security reasons (don't choose the admin user).
It will change this into an LDAP format with commas automatically.
Then click the Set Password button (this does not actually CHANGE the password, it's just so you can enter what the password CURRENTLY is).
Click Set Password
For the LDAP Group browse button, you will choose the appropriate eDirectory LDAP GroupWise object that belongs to the LDAP server(s) you have already defined in GroupWise.
Click OK
Now click OK again.
Click OK again (it will keep taking you "up" one level).
Click OK again.
