Error when upgrading from TokuDB 7.5.2 to Percona tokudb-56-5.6.26-rel74.0

I’m simulating an upgrade from TokuDB 7.5.2 to Percona-Server-tokudb-56-5.6.26-rel74.0.el7.x86_64. Everything looked fine except for one table in which I get the following error when trying to access it:

Incorrect information in file: ‘./mailer/log.frm’

I tried a REPAIR TABLE but it didn’t worked. So I stopped Mysql and copied this file again from production server. It failed.

I’m pretty sure that it isn’t corrupt since the same file/table is working fine with TokuDB 7.5.2.

Any ideas about how to fix this issue?
