Describe the issue or problem
After updating from version 3.3.0.10 to version 3.5.0.4, I noticed the following table appeared:
total 9.9G
1.4G -rw-rw---- 1 mysql mysql 1.4G May 19 21:06 metrics_old.ibd
Is this table used for anything? Can I delete it, or should I save it in an appropriate location for future reference?
What application are you using?
OJS 3.5.0-4
