In looking everything over, I found my xenforo database on the active site to be around 38 gigs. The database on the new server is around 34 gigs.
A backup from about a week ago was 31/32 gigs (ssh'd .sql file).
I'm wondering if anyone has any idea on 1) why the database size may shrink in this circumstance or 2) why a database size might unexpectedly increase, 3) if the database size listed in cpanel may be incorrect.
I'm concerned about data loss/corruption. My host did a test reimport of the database and got approximately 34 gigs again, with a slight increase in xf_posts.
Edit: In looking over the second import the discrepancy is smaller, but there still is one. 38.5 v 36.5
