AEM6.x Migration

• How to Rebuild a Pre-Existing AEM+Mongo Cluster
• or migrate from Tar to MongoDB or MongoDB to Tar"
• or migrate from 5.6.1 or 6.x to 6.x via data migration instead of jar upgrade

1. (Mongo to Mongo only) Remove one replica from the replica set and delete/recreate the db
   1. Remove the replica node from the set: http://docs.mongodb.org/master/tutorial/remove-replica-set-member/
   2. Validate that no other nodes in the set consider that node to be part of the set anymore. Log into each node in the cluster via mongo shell and run rs.status() to validate that the node that was taken out is not in the cluster any longer.
   3. Drop the aem database on that node http://docs.mongodb.org/manual/reference/command/dropDatabase/
2. Re-add the database with the correct user permissions (do not add the mongo instance back to the replica set)

This will only log the start and the end of the sync cycle, no progress indication logged.

You'll get the following:

Clean up unreferenced checkpoints

1. Download or build oak-run 1.x matching the version you have installed in your Oak environment.
2. Stop all AEM instances
3. Upload the oak-run to the AEM server if using TarMK or MongoDB server (if using MongoMK)
4. Run this command to cleanup unreferenced checkpoints on TarMK:

java -Xmx4096m -jar /apps/staging/oak-run-1.*.jar checkpoints crx-quickstart/repository/segmentstore rm-unreferenced

Clean up unreferenced checkpoints on MongoMK:

Set up your file structure for the innerParsys component:

innerParsys
	-> parsys
		-> new
			- _cq_editConfig.xml
			- .content.xml
		- _cq_editConfig.xml
		- .content.xml
		- parsys.jsp

Set up your file structure something like this:

/apps/your-site/components/page
  -> yourPage
      -> clientlibs
          -> js
              -> customSidekickDialog.js
          -> .content.xml
          -> js.txt
      -> customDialog.xml
