We didn't bother upgrading to 8.5 but want to upgrade to v9 anyone got any experiences of upgrading from 8.1?
Thanks
You should not have any problem upgrading from 8.1 to Orion 9.
I have had Customers upgrade from 8.0.2 to Orion 9.
Their only issue was it took E.G. A database of 10GB can take over an hour to upgrade. 20GB Takes 2hours, etc...
But you should experience this issue as you are already on 8.1. There was a large overhaul to the Database structure going from 8.0.2 to 8.1.
