Re: Migration EV Cluster 10.0.2 to 12.1.12

The_Boulon · ‎01-11-2017

Hello,

In a few weeks I have to migrate an EV cluster (2008 R2) in 10.0.2 to EV 12.

I know that you cannot "just" upgrade like that and that EV12 cannot be installed on W2K8R2 but on a WS2012/R2. No problem at all for this.

My main problem (if we can say that is a problem) is the add in.

As the company is on his way to migrate to exchange 2016 and O365, I was asking myself: can I use the EV12x in O2016 vO365 with EV 11?

I brief, I was planning to do it like that

Upgrade Office 2007 to 2016 v Office 365 (with EV12 Add-In - TBC)
Installation Exchange 2016
Upgrade EV11.x to 12 via Migration Wizard
Make the final changes to reflect new infra (Add DD as VS and New Exchange Servers)
Add new EV to Backup
Deploy Outlook Add-in
Add New Exchange Servers to EV12
Migrate mailboxes (Exchange part)
Migrate archives from VNX to DD
Check if all OK

That's in 'raw' how I woudl do it. Just that add-in question that remains.

Cheers!

Hi,

you should check the compatibilty charts.

Check windows email clients

Hi,

I already checked all of that :)

My main concern was the add-in not working with an oldest version of the server.

I already had the problem that an add-in in 10.02 was not working with an ev server in 10.0.4

So yes, I prefer asking now and get an answer like: the add-in for v12 will not work with a server in v11. or a yes, it will work.

Safety first :)

Anyway, thanks for your reply.
