Upgrade Gerrit form 3.11.3 to 3.12.X

[Guy Levkowitz]

Hey

We are on Gerrit version 3.11.3

We want to upgrade to Gerrit 3.12.X

Do you suggest upgrading directly to version 3.12.2? 

Or maybe it more safe to do first upgrade to 3.12.0 

Also about H2 to H2 v2  - if we do an offline upgrade with a full reindex do we need to do anything else ?

I just upgraded 3.10.0 -> 3.11.5 -> 3.12.2. It was mostly smooth. Before going to 3.12.2, I moved all the cache files to a different location. It did an online reindex, which slowed the server down considerably until it finished.

I don't think you need to go to 3.12.0 first.

Thanks for the update,

Small question:

Have you been defining the new plugin: cache-chroniclemap  (as suggested at: https://www.youtube.com/watch?v=T2ApofhyF10) ? 

Or for now just using the built-in H2 v2 version ?

I just used what came in the official docker container, working great.

Thanks for the update 

Small question - our merge icon background was green now it is gray 

also, the open status was "Active" blue, now it is Orange - is this how it should be - did you see these changes of the colors?

Yes, that matches what I see in my installation.
