Pre-upgrade maintenance task
Hi all,
I am trying to upgrade AEM 6.2 to 6.5. If I didn't run Pre-upgrade maintenance task, will there be any issue in upgrading?
Edit: What I mean is how about if I didn't run this com.day.cq.audit.impl.AuditLogMaintenance? how can I check whether my AEM run on crx2 or crx3 mode?

Thanks.
