Migration of 8.8.11 from Centos 7 to Ubuntu 20.04

[smclinden]

My understanding is that I need to have the same version including the minor release number on the new server. But I can't find a Open Source version of 8.8.11 prebuilt for Ubuntu 20.04.

Pointers or suggestions would be appreciated.

Thank you!

Or is it possible to export all the data and then import it into a newer release of Zimbra?

8.8.11 is an extremely old version and a build was never created for Ubuntu 20.04 for this release.
If you need to stay on 8.8.11 you can use Ubuntu 16.04 but we recommend upgrading your server to 8.8.15 which supports Ubuntu 20.04.

I assumed that this was the case. I guess my question is, if I follow the procedure outlined in https://rants.tech/migrating-opensource-zimbra-8-6-0-on-centos-6-8-to-zimbra-8-7-1-on-centos-7-safely-and-with-no-downtime/ can I import the accounts and mailboxes dumped from 8.8.11 into a new instance of 8.8.15?

Thanks!

There are a number of ways to do the migration.
You can use the link provided but It was done by a community member some time ago so I recommend doing your diligence in testing the steps.

You also can use a rolling migration, which is outlined in:

Again I recommend doing your diligence in testing all of the steps.
