I just upgraded a large site to 4.7 (without any issues in the upgrade process by the way). The new "System Status" admin screen gives a warning as follows:
"Your database is configured to use the MyISAM database engine. CiviCRM requires InnoDB. You will need to convert any MyISAM tables in your database to InnoDB. Using MyISAM tables will result in data integrity issues."
This is news to me. I took the database over from another person and have upgraded it a number of times already. I looked at the database and it does have some strangeness. For the most part, each
civicrm_ table is listed as INNODB, all the
log_ tables show up as ARCHIVE, and at the bottom the global setting seems to be MYISAM. The one exception is the
civicrm_system_log table, which is listed as MYISAM.
Is this going to cause problems, and is there an easy way to get everything on track?
