EV Upgrade for multiple servers

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 ...

    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.

    regards

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 :-)
