So a quick question.

When upgrading a cluster. All my members are current 5.2. So upgrade the "Master" first I figure and then each slave in turn.

Do I need to upgrade the slaves right away or will things function properly in a mixed version cluster.

Reason I ask is that I want a little time to make sure the upgrade functions properly with my "Slightly" tweaked setup.

In test setups we had quite a few mixed combinations running, and saw no problems - however keep in mind that a testsetup is different from production!
The clusterstack should have no problem with running 5.x and 6.x - but I would suggest to quickly get everything up to the same version.

I probably would take the master/a slave out of the mail-flow (adapt the MX-records, change the configuration of the balancer you have in front..., or just keep the 'postfix' service masked, then tweak and test the config as good as possible and take it back into the mail-flow

I hope this helps! (Else please open a new thread)
Thank You!!!

That makes sense to me and if I run into anything of course I will start a new thread.

Thanks for this wonderful product.

Internet Explorer 11 doesn't show the Quarantine Page, it stays blank.
Google Chrome + Firefox are fine ...
Maybe you should note this somewhere in your Release Notes or Documentation ...
