Hi All,
This is an upgrade question.
All the EV Servers are part of the same EV site. However each server has Vault Store DB located on SQL Servers at the local locations. Current EV version is EV 11.0.0. OS of EV server is Windows Server 2008 R2. I am assuming that I would first need to upgrade EV in-place to 11.0.1 before migration to new server running EV 12.4
The goal is to upgrade EV to latest version (EV 12). In order to perform this upgrade, is it possible that the upgrade can be done one server at a time? - for example, migrate one server to a new server running EV 12 on Windows Server 2016 and upgrade its relevant VS DBs and then finaly perform the migration of the Directory Server to EV 12 once all other servers are done? I would like to perform the upgrade in phases spread across weeks instead of all at once if possible.
Thanks!
Regards,
VJ

Hi,
they way would be:
inplace upgrade ALL to 11.0.1 on Win 2008
move server to Win 2012 (directly to 2016 is possible although not supported for Version 12 - not recommended)
Upgrade to ALL to 12.5
Move to Win 2016 or newer, or keep 2012 aslong as it isupported.
Mixed configurations, like 11.0.1 and 12.5 will not work, since you will have different database schemes.

Thanks for reply... would like to know more about what you have mentioned in this line "Note that you must progress through each iteration of EV because database schema updates will take place at each version. " Is it not possible to migrate directly from EV 11.0.0 to EV 12.4.1? I understand that Server Settings Migration Wizard will not be compatible as it requires minimium of EV 11.0.1. I was thinking of manual migration method.

Hello,
As far as I know, you can go from 11.0 to 12.4 directly. I'm not sure about using SMW to do this, but the SMW documentation should have this information.
12.4.1 is a 'maintenance release' (like a Service Pack), and requires EV to be on the 12.4 release first.
I always had the impression you could not mix EV versions on servers if you were using 1 site with a number of EV servers. 1 site = 1 Directory database. The upgrade would upgrade ALL EV databases (no matter where they are located) to the new version. This does mean the EV binaries also will need to be upgraded. In your situation, the complexity with also needing an OS upgrade makes it more difficult.
Perhaps you can have Rick assist as consultant :)
