Came across this video where the upgrade of two projects from AEM 6.2 to 6.5 is discussed.
- what was the approach they followed
- what difficulties and issues they encountered while upgrading it to 6.5.
- Which tools they have used
- what went easy to migrate.
Many points like this were discussed.
It might be helpful for people who are going to start the upgrade to 6.5.
