migrate my control room presets from 10.0 to 10.5

Upgraded to 10.5 for the sole reason of getting rid of that annoying click in the time line/measure ruler and avoiding activating cycle mode. However, that created a second annoyance.

How can I migrate my control room presets from 10.0 to 10.5?

All the inputs/outputs I had set up, control room setup for two sets of monitor speakers, my headphone mixes, etc. - gone. If I’m doing something wrong on the updates, let me know. I just do what the update manager tells me to. Why wouldn’t an update manager tend to all of this?
