So, one of our 4 production DDC's was upgraded, but DB not updated, why can't I access Studio on any DDC's.

We have 4 DDC's in our production environment.  We are running XenApp 7.15.5.000 in prep for an upcoming CU7 upgrade, 1 of the DDC's was upgraded, but the database automatic upgrade nor the database generated scripts were run.  However; Citrix Studio in none of the DDC's will display the contents of the farm, they all prompt to run automatic updates or create the manual scripts to update the DB backend.

Thankfully users are not impacted to use Citrix and can launch published apps, however; this means we can't manage the farm.

I would have understood if we updated the database, but was simply the node that was done.

Is there a way to get the other 3 DDC's displaying Studio contents correctly?  Or is there a way to degrade the 1 DDC without impacting the farm and again, getting Studio contents displaying correctly?

Thanks in advance.  Though we followed the doc, that's why we stopped the upgrade at that point and didn't run the DB scripts.  I was able to view Studio contents until the session timed out on the DDC I was on which was not the one upgraded.

Thanks in advance.
Learning curve for sure, thought this part would have been independent.
