New support portal does not show old tickets, and SRM only shows 90 days

I suppose I can understand why Bentley decided not to migrate closed Service Tickets into the new portal. I disagree, but I can understand...

The old Service Request Manager now only shows tickets for the past 90 days? Where did the rest of them go? If that service is going offline, I want to document ALL of my previous Service Tickets. One, just to have a record. Two, so that if I run into a similar issue, I can look at the old tickets to see if I have a solution, or if I need to file a new ticket.

Where is the rest of my Service Ticket History?
