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

(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/
Re-add the database with the correct user permissions (do not add the mongo instance back to the replica set)

Golang Workers / Job Queue

A running example of the code from:

This gist creates a working example from blog post, and a alternate example using simple worker pool.

TLDR: if you want simple and controlled concurrency use a worker pool.

Generate private key (.key)

# Key considerations for algorithm "RSA" ≥ 2048-bit
openssl genrsa -out server.key 2048

# Key considerations for algorithm "ECDSA" ≥ secp384r1
# List ECDSA the supported curves (openssl ecparam -list_curves)
