Redis move all keys from one database to another

Question

Is there a command to move redis keys from one database to another or is it possible only with lua scripting??

There has been this type of question asked perviously redis move all keys but the answers are not appropriate and convincing for a beginner like me.

Answer 1

u can use "MOVE" to move one key to another redis database;

the text below is from redis.io

MOVE key db

Move key from the currently selected database (see SELECT) to the specified destination database. When key already exists in the destination database, or it does not exist in the source database, it does nothing. It is possible to use MOVE as a locking primitive because of this.

Return value

Integer reply, specifically:

• 1 if key was moved.
• 0 if key was not moved.
