ZCM appliance 11.3 to 11.4 migration

I started by going through the "preparing the ZENworks 11.3 appliance for migration" by downloading he ZDC. After getting the 11.3.2 ZDC and getting it to run I found that there were problems encountered. The "systemfiles report" lists 3 missing files and 12 inconsistent files. Are these a problem? If so how do I fix it?

Should not be an issue as long as the database is fine. Take a snapshot
beforehand though, just in case.

Re: ZCM appliance 11.3 to 11.4 migration

Thanks!

The "vastorage" disk created in the process, is there anything special about it? (say

I also see a note that says "If the ZENworks 11 SP3 Appliance was configured with an additional or external disk for content repository, then ensure that you mount the disk on the ZENworks 11 SP4 Appliance.

For example, /dev/sdb1 mounted to /var/opt/novell/zenworks"

How does this differ, they contain much of the same information. I'm confused.

No. Any external repo is a different kettle of fish and that has always
been the same. Let me elaborate:

With 11.sp4 Novell moved to the same appliance architecture as other
appliances, namely Filr, iPrint etc.

Before SP4 a ZCM appliance had at least one disk that held both the
application code AND user data. The user might have had the content repo
on another disk, but the database and config shared the same disk as the
OS.

The SP4 migration is actually a two-step process:
1. You add a disk to the old appliance
2. You download and run the migrator tool. The tool copies all user data
to the new disk.
3. You detach and move that disk (or copy) to the SP4 appliance VM
4. You start the VM.
5. The VM will find the new disk with data and use that.

The docs explain this pretty well apart from the fact that they omitted
some stuff like assuming you know how to add the disk. These are the
quirks I noted and reported to the doc people:

1. Assumptions that the reader can read between the lines (that you
actually need to fdisk, format and automount /vastorage on an appliance
where most tools are missing)
2. Discrepances between docs and actual commands (There is no
zdc_verifydb)
3. Scary warnings that the disk (ie /vastorage) is not empty because of
lost+found
4. There is no message when the copy is complete. It just sits there at
100%, but since it did dismount /vastorage and had COMPLETE for all I
assumed it was done.

Having OS and data om separate disks makes upgrades cleaner in the
future.

Re: ZCM appliance 11.3 to 11.4 migration

Unfortunately the outline you describe is not the whole story. This has me really grumpy! I sized the new disk according to the documentation (and made it bigger expecting growth) and expected everything to be copied over including the database and content repository.

The migration utility does NOT copy all the needed data. The content repository and database are not copied for instance. You MUST mount the old disk (mounted at /var/opt/novell/zenworks) on the new appliance for it to function. This will NOT make the next upgrade easier. It also means my appliance is now about 50% larger than I was expecting with the new "vastorage" disk and the old external disk from the old 11.3 appliance both mounted.

If following the instructions was not what I was supposed to do... the what was I supposed to do? The simple outline of instructions

The SP4 migration is actually a two-step process:
1. You add a disk to the old appliance
2. You download and run the migrator tool. The tool copies all user data
to the new disk.
3. You detach and move that disk (or copy) to the SP4 appliance VM
4. You start the VM.
5. The VM will find the new disk with data and use that.

will not result in a functioning appliance in an environment were the appliance is the primary server (and only server).

Not sure that I follow... The calculations for disk size in the docs are
waay off. I ended up with a vastorage twice as large as the calculation.
Forgot to mention that.

My content repo and database migrated just fine. Was your repo on the
appliance or on a separate disk?

Re: ZCM appliance 11.3 to 11.4 migration

I'm not sure how to answer the question. When I set up the appliance, a second disk was created and mounted at /var/opt/novell/zenworks. It contained almost 500 GB of information. After running the migration utility, the new disk held 13 GB. To make the new appliance function, the old "second" disk had to be mounted onto the new appliance. Now the the appliance is much larger than anticipated. The migration process did not really migrate much.

That is your content-repo. You did set up a disk to be used as a content repo so the following part of the migration docs appies:
https://www.novell.com/documentation/zenworks114/zen11_upgrade/data/b1g648uv.html

"4.If the ZENworks 11 SP3 Appliance was configured with an additional or external disk for content repository, then ensure that you mount the disk on the ZENworks 11 SP4 Appliance."

So. On your 11.3 appliance, you had two disks. One for OS, System files, config and database and one disk for the content-repo.

On your new 11.4 appliance, you have three disks:
One for OS, one for System files, config and database and one disk for the content-repo.

In your case, the /vastorage could be rather small as the content-repo, which is usually the largest is'
on another disk.

This is also mentioned in the space calculations: "If any of the directories are part of the mounted disk partition, then its size can be ignored while calculating the new disk size."
