# Migrate database
|
||
|
|
|
||
|
|
To migrate the database, you need to add `migrate` command.
|
||
|
|

|
||
|
|
The pg backup has another great feature: migrating your database from a source database to another.
|
||
|
|
|
||
|
|
As you know, to restore a database from a source to a target database, you need 2 operations: to start by backing up the source database and then restoring the source backed database to the target database.
|
||
|
|
Instead of proceeding like that, you can use the integrated feature `(migrate)` that will help you to migrate your database by doing only one operation.

# In production, it is advised to lock your image tag to a proper
|
||
|
|
# release version instead of using `latest`.
