Upgrade to 1.5 from 1.2.2? (1 Viewer)

[mickelin]

Hi,
I have a rock solid MP 1.2.2 system , a multi-seat with one server and five clients. I'mconsidering an upgrade (I know, if it aint broke, don't fix it...). Will the 1.2.2 client work with an upgraded 1.5 server, or do I have to upgrade them all at the same time?

Almost certainly not.
[edit: to be clear - I'm saying you will need to upgrade]

Thanks, I guess I will have to plan for a full weekend and send away the family... And make sure to have good backups before I start.

No.

Yes, that is always recommended.
Also, don't forget to stop the TV service before upgrading, and check for plugin updates immediately after updating.
