Exporting closed tickets to a separate database.

Good morning all, I wonder if you can assist? Our database is currently running high and we wish to keep it below the 10 gig threshold SQLExpress has. I have tried the following all with minimal to no success: shrinking the database data delete from aaaaccsession delete from auditrecord delete from recentitems delete from errorlog archiving all closed tickets older than 2 years. Can you please advise on what else can be done to reduce the size of the database? Is there a way to move all closed tickets older than 2 years to another database using SQL, which would then be accessible if required? Any advice or assistance would be most welcome.
