Migrate Thunderbird From Win 7 Partition To Win 10

My Win 7 partition barely functions. Something is broken. It is installed on a Ryzen PC and was working fine up until recently when it barely boots at all. I guess Micro$haft has actively borked disk performance on the Ryzen or SOMETHING.

Whatever.

I knew I would be forced to move to Win 10 eventually, so I installed it on a second SSD in the system at the same time as I isntalled win7. But now I can't really use the Win7 partition to mozbackup my Thunderbird accounts and emails and restore them into the Win10 install.

Any way I can do that from my win10 boot?

Thanks

 

You cannot use MozBackup on the Win7 partition/disk from the Win10 partition/disk.
Even if it was possible, MozBackup doesn't support Win10 - development stopped more than 7 years ago.

 

Oh crap thanks. How do I do it then? I would think that moving all the Tbird data files from the win 7 install onto the win10 one should work?

 

It's worth a try.

 

Are you using IMAP accounts or POP3 accounts in TBird?

 

Here is how I've migrated Mozilla Thunderbird from one PC to another. It's actually pretty simple. You're just going to "pull a fast one" on Thunderbird, and it won't know the difference.

Note: These instructions assume that your Windows 7 drive is now a data drive attached to your system (Windows 10 is on C:, and Windows 7 is on D: ).

1. In Windows 10, launch Thunderbird and create a new user account. You can use any fake e-mail address (you won't be using it, anyway). Exit Thunderbird when you're done.
2. Launch File Explorer and go to C:\Users\[user name]\AppData\Roaming\Thunderbird\Profiles. Note: AppData is a hidden folder; File Explorer won't show it to you unless you click on "View" and select "Hidden items".
3. Here you'll see a folder named [random letters and numbers].default . Make note of the folder name, and then delete the folder.
4. Open another File Explorer window and go to D:\Users\[user name]\AppData\Roaming\Thunderbird\Profiles .
5. Here you'll see a folder named [random letters and numbers].default . This is the Thunderbird data store from your Windows 7 setup. All of your configuration files, mailbox data files, address book(s), message filters, etc. are saved here.
6. Copy the Thunderbird profile folder from D: to C:, making sure that it goes into the location specified in step 2.
7. On C:, rename the old Thunderbird profile folder to the same name as the new Thunderbird profile folder.

That's it. Launch Thunderbird now. It should have all of your messages and work just like before with no setup required.

 

Dude you are a GOD. THANK YOU SO MUCH!!!!!!!!!!!!

 

Not a god, just someone who's been doing this stuff for a long, long time.
