******************************************************************
|
|
|
|
This script is solely for the migration purpose only.
|
|
This is a 1 time migration of volume data from v0.13.2 => v0.14.x
|
|
|
|
Assumption:
|
|
1. Postgres data volume name ends with _pgdata
|
|
2. Minio data volume name ends with _uploads
|
|
3. Redis data volume name ends with _redisdata
|
|
|
|
Any changes to this script can break the migration.
|
|
|
|
Before you proceed, make sure you run the below command
|
|
to know the docker volumes
|
|
|
|
docker volume ls -q | grep -i "_pgdata"
|
|
docker volume ls -q | grep -i "_uploads"
|
|
docker volume ls -q | grep -i "_redisdata"
|
