Hello,
Do you mean you want to move a database to another disk to release 106GB of the disk space? If so, I recommend you do full backup for your database on schedule to truncate unreuired logs file so that it can release disk space.
Here is the article for your reference.

If there are other exchange servers, you can also move mailbox to another database on another server.
You can also export your mailboxes to pst files.
If I have any misunderstanding, please free let me know. And please express your issue in english.
