Thanks for your reply Giz,
I believe my steps are
1, upgrade PHP5 to PHP7
2a, upgrade MySQL Version: 5.7.41 to ??? or
2b, migrate to MariaDB version ???
3 Upgrade to UBBT8 when available
4 migrate to almalinux8 or what my host recommendation is.
Step 1 is to contact helpdesk and ask for a backup and change to PHP7. I don't want to do these things my self.
I'll do it in a couple days.
Do you have any recommendations regarding the procedure?
Thanks
