Hello Jay,
below my notes when I solved the same issue few years ago.
The problem is DB, we're using RDS now.
Might need some adjustments or might not, please check the actual docs.
dump db from container
restore DB to RDS
make sure you get correct encryption key from current installation
check all DB’s user - new host must be allowed - added new users retool_user@hosts
Check connectivity between eks and RDS
just deploy in any convenient way retool to k8s - manually, helm etc and set all env variable
Thanks so much for sharing knowledge on these steps here, @Punka! Now that this is available here in the forum I'm sure it will help many others going forward as well.
Glad this is solved on your side @Jay3112 and thanks for asking here!
