Upgrading from 3.6 to 3.7 but the filtsrv migrate option fails.
I have unloaded filtsrv then filtsrv migrate which gives an error
migration failed" and advises to unload filtsrv and retry. I have
this but it makes no difference.
NW5.1 SP5
NBM 3.7 SP2
RW replica on server

The schema also failed to update. I attempted to run it manually.

addrulecontainer failed with error -604
schema extention failed with error -604

Thanks in advance
