What would be the best way to upgrade from 2014 R2 to GW18?

I have a few options to upgrade GW2014 R2 to GW18 ...

1) Upgrade GW2014R2 in place on SLES11 OES2015 to GW2018 then migrate GW2018 to a new SLES2018 server ....

or

2) Build a Clean SLES 2018 server attach my 2014R2 Volume to the New server then do a Clean New install of GW18....

is one better than the other or are there any pitfalls to either process?

Hi Lramm,

Welcome to the Micro Focus forums!

Those are good questions.

Usually, one approach may offer benefits over the other. A couple of
answers from you will help me better understand your situation.

1) Is the GroupWise volume on the current server using NSS or native
Linux?

2) Is the new server going to be pure SLES or will it also be OES? By
"SLES 2018", do you mean SLES 12, SLES 15, or OES 2018?

3) If you mean OES 2018, do you plan to use NSS for your GroupWise
Volume?

Personally, I don't like to do two things at once. If something fails,
or just doens't work like it did before, it's much more difficult to
deal with two variables. As such, I would update to GW18 on the current
OS first, let it run for a while and get comfortable with it, and then,
in a totally different step. Update the OS.

But just a note: There is no such thing as "SLES 2018". I hope you mean
OES 2018?

Re: What would be the best way to upgrade from 2014 R2 to GW

First Thank you for the correction it would be SLES12 no OES2018 "too much 2018 on the brain...."
My Groupwise volume is native Linux.

The new server will be SLES 12 stand alone.

Just a comment:

I'm always dumbfounded how people with a valid OES license can opt to
throw all the advantages of NSS in the bin and run grouppwise on
filesystems that simply not in the remotest ways can compete with NSS.
Neither by performance, stability, manageability nor features. It's
beyond me.

Great!

Either way you do it, there are two separate processes: Upgrade and
Migration.

First approach:

> 1) Upgrade GW2014R2 in place on SLES11 OES2015 to GW2018 then migrate
> GW2018 to a new SLES2018 server ....


1a) Do basic health check
1b) Install GroupWise 18 software on OES 2015
1c) Do the upgrade
....
1d) Do basic health check
1e) Install GroupWise 18 software on the SLES 12 server
1f) Shutdown GroupWise 18
1g) Attach the GroupWise 18 volume to the SLES 12 server
1h) Do the upgrade again (new IP addresses?)


Second approach:

> 2) Build a Clean SLES 2018 server attach my 2014R2 Volume to the New
> server then do a Clean New install of GW18....


1a) Do basic health check
1e) Install GroupWise 18 software on the SLES 12 server
1f) Shutdown GroupWise 2014
1g) Attach the GroupWise 2014 volume to the SLES 12 server
1h) Do the upgrade

As you see, the second approach has quite a few fewer steps however I
agree completely with Massimo that the first approach is the preferred
one. If you encounter issues using the second approach, it may be more
difficult to identify the source as you are using new GroupWise
software and new SLES software.

You may get some additional ideas from a new Cool Solution I authored.

Having made the comment, perhaps you could elaborate for others reading
this thread?

- Data on the GroupWise volume does not need to be accessed by end
users.
- GroupWise doesn't take advantage of trustee rights.
- Best practices dictate that salvage be disabled

What other NSS features make it a more appropriate choice?

As for performance, I have not seen any comparisons. In your
experience, what performance differences have you seen with NSS as
compared to native Linux filesystems?
