Planning upgrade 9102 > 9208-10

We are planning to upgrade from v9102 to v9208 or later, though I've read quite a lot of complaints of SDP admins having quite a few problems after upgrades. I won't go for anything on the live server before doing a test, though I wanted to get advice and any tips/suggestions/guidelines from the team here.

Sincerely,
