I would like to archive data that we no longer need on a regular
basics.
We will need to query it maybe once every three or four months.

I would like to move the data from Current_DB.mytable to
History_DB.mytable.

What happen with DB's that we hardly use?
How much resources MySQL assigns it?
Is there a way to make that History_DB dormant?

What other options We have?

Thank you all,

Don't use it. But that won't change the amount of disk it uses.

You could take dumps of the history DB with mysqldump, put the
dumps on a removable medium like a tape or CD, and then drop the DB.

But I'm lazy, and disk is cheap, so unless we're talking about tens or
hundreds of millions of rows in this history DB, I wouldn't bother. It's
easier to buy a big disk once than fuss with restoring, analyzing and
dropping data every few months.
