Or you can do a File - File Operations - File Copy with dates in the future it will do a better job than year-end-copy. The YEC has to try to work around reconciled vs unreconciled transactions and the Copy doesn't. Unreconciled transactions and investments transactions won't be cleared out. Most of the users here recommend you just hide the accounts. Just make frequent backups.
