Can I restore two different backups to one instance of QBO? I have two backup files for the same company from two different time periods that I want to combine. Thanks!

Hello there, MFHOATreasurer.

Currently, the option to restore two different back up files in one go is unavailable. Although you can do that one at a time. There will also a notification if you have the duplicate transaction every time you restore your file.

You can follow the steps in this article: Restore a backup of your company file.

Let me know if you have further concern about restoring back up files. Glad to lend a helping hand. Have a good one.

You have to restore each of them on a separate QBO account. Then utilize the migration tool from one account to the other one.

I have a similar issue.  

I was running Quickbooks Server on a machine that also runs DNS and was having issues with the DB Server and DNS causing the DB Server to fail to start.  So, I moved the Database Server and DB files to a new server that I spun up in a Hyper-V Virtual Machine.  I uninstalled the database server on the old server so I expected the clients to find the new server, which most of them did, except on client machine.  It was tied directly to the DB files, that were still on the old server.  I know I should have removed them, but I thought with the DB server no longer watching those files, that no one would be connecting to them.  This user however, found the files and mapped directly to them.  So everything that she has input is of course not going into the correct database.

I need to combine the database that she is working in with the copy that I moved to the new server.  From what I read in this thread, if I open the DB on the new server, and restore the old DB it should merge the two announcing all of the duplicates along the way, but it should add all of the information that has been added to the old db.

Did I read that correctly?  Would this work?  

Sorry.  Double Posted...

I appreciate you for providing complete information about your database files, bwelch.

Let me share details on how you can combine your backup files from your old DB server to the new one. This way, you'll be able to use the new DB server that contains the updated file.

Based on your description of the issue, it seems that you're using our QuickBooks Desktop. 

When you open the DB on the new server and restore the old one in the new server, merging it is not an option. However, you can use a third-party application to import and export information in your new company file.

You can copy and use accounts, lists, templates, and preferences from an existing company file to a new one. To do this, kindly refer to this article for the detailed steps: Create new company files from existing ones in QuickBooks Desktop.

Please know that I'm always here to help if you need anything else. Take care always, bwelch.

Utilize one of these 3rd party tool to migrate the data between QBW files. You may export only certain transactions data from one data file to the other one. Make sure to set the filters to avoid any duplication.
