Can anyone who has completed an upgrade to 8.6 call manager confirm that you need to fully install and switch versions/reload the publisher on 8.6 before you attempt to load the s/w on the subscriber and swiitch versions ?
before 8.6 you can upload the s/w to the inactive partitions on pub and subs then do the switch versions, i dont think you can do this when upgrading from pre 8.5 to 8.6.
Thanks for the reply, have you actually tried this ? This is how I did my upgrade, switching the publisher works ok and comes back on 8.6 , when switching the subscribers this Comes back with an error software version mismatch, must change publisher before switching versions. If you read the 8.6 installation readme doc it appears to say that the publisher must be upgraded first and version switched before upgrading and switching the subs.....
One thing I also notice when installing the 8.6.2 os on the inactive partition is that once installed it shows as the same version I am upgrading from ( 7.1.3). ??? , I switched on the pub and then it shows as 8.6 on active and 7.1.3 on the inactive, when you try on the subs it throws up the error message above????
