How to "upgrade" to the contrib module without loosing the history?

Hi all, I have a Drupal 9 forum that goes back 21 years in user comments and posts. There is a lot of content.

When I install activity tracker it only show activity going back 2 year 11 months. I'm wondering if support would be able to figure out how to force the indexing process to not stop after this date. My server is good, php memory etc has no issue.

I'm pretty certain it's a forum related glitch likely when I updated to Drupal 9, two years 11 months ago.

Any suggestions on how to find out where to look for what's blocking activity tracker from indexing past 2 years, 11 months?
