I think it's worth to try, but make DB backup. 
I tested a bit (e.g 1.1.4-SNAPHOT to 1.2.0) against an existing DB .. was ok. No guarantees ;-)

another thing is:
export your installations from old
(re)create push-app/variants and import devices

Hi,

Any Aerogear UPS migration guide from 1.1.0-Final to 1.2.0.Final? The only
relevant info I can see is here:

https://github.com/aerogear/aerogear-unifiedpush-server/tree/1.2.0.Final/migrator

But it looks outdated. Where can I find more instructions? I may be able to
help updating the document but I need someone familiar with the process to
provide more details on the migration path from from 1.1.0-Final to
1.2.0.Final.

Thank you.
