How to Remove and Re-Attach Exchange 2013 Database?

Question

A database is being copied from a location that is too small to external storage.
Due to management wishes to prevent administrative mistakes, a journal DB that we need to keep for compliance reasons needs to be removed from EAC access.  I understand that the
Remove-MailboxDatabase command will accomplish this.
However, management also wants to be able to re-attach that database at a later date. 
Can this database just be re-mounted, or is it necessary to create a NEW database and bring the mailbox info from the old DB to the new one?
Thank you.

Destroying/removing the fact that the Exchange Journal DB ever existed on the server is a drastic way to go if you still want to access the data in the future.  However if you wanted to do that then you would recover the data via RDB method and you
can see more on that here

The only other methods to gain access to that EDB in the future would be to
1. Move it then dismount it so that its not taking up any resources and can also be backed up as a flat file.  Then when needed just remount the DB, do you work and dismount again.
2. Or use a 3rd party utility like DigiScope that can open the offline EDB without needing to be on an Exchange server.
Search, Recover, & Extract Mailboxes, Folders, & Email Items from Offline Exchange Mailbox and Public Folder EDB's and Live Exchange Servers or Import/Migrate direct from Offline EDB to Any Production Exchange Server, even cross version i.e. 2003 -->
2007 --> 2010 --> 2013 with Lucid8's
