Failed update to DCS 6.7.3

Hi guys,

Long story short we had our upgrade fail. As part of rollback we had planned to restore to snapshot or backupo but ultimatly these both failed.

We have 2 DCS managers and the secondary was up and the DB was up as well so no biggy - re-installed DCS 6.7.2 and installed the TomCat server only usng the backed up files and server xml. All good.

Login this morning to try again and I get an error when kicking off the upograde saying to do this on the primary manager which isnt TomCat only. Attempted this on the secondary server and same problem.

1. How do I make one of the managers the primary  DCS manager ?

2. How can I upgrade to 6.7.3 if both managers are TomCat only ?
