What is the impact to upgrade ?
We have a lot of configurations applied in 6 appliances with control through ePO.
What is the Impact on:
- SMTP Protocol
I mean, when apply the upgrade, move some of configurations ?
If you are starting from 7.5, then upgrading isn't too much of a chore. Make a backup of your configuration first, or if you are using virtual appliances, you can do a snapshot so that you can roll back easily if you have a problem. 7.5 and 7.6 look almost identical and for the things you mentioned, work the same. Since you manage with ePO, you will upgrade the appliances and then reconfigure the connection with ePO and check in the new extension and import the policy.
