AEM 6.2 Sidegrade

[andrewj40704587]

Hello all,

I am building a new infrastructure stack with new / upgraded host VMs. What are your thoughts on migrating AEM to the new servers? I see 3 options:

1. Copy/paste or clone the instance from one server to the other
   • This would be the easiest and quickest option
   • Any issues we have with the instance (stability, corruption, etc) will persist
2. Build new / clean AEM instances, and use packages to migrate content between the two stacks
   • This would ensure there are no lingering issues or questions from previous AEM upgrades (we in-place upgraded from 6.1 to 6.2) or having been up and running for a long amount of time
   • This would lose version history
3. Build new / clean AEM instances, and use crx2oak to migrate content between the two stacks
   • This should also ensure no lingering issues from previous upgrades or extended wear and tear, and would keep version history
   • We tried this once during our 6.2 upgrade, but many things broke because it was going between 6.1 and 6.2. It may be a harder sell to decision makers.

Any other options or thoughts are welcome. Thank you,

Andrew

Hi Andrew,

I would take your option 1, as option 3 is likely to have the same issues regarding stability. It will just make sure, that you have no issues on a TarMK level on your new instance, which we can typically rule out, because otherwise you would see these issues on your existing instance as well.

kind regards,
Jörg
