Hey, gurus!

Unfortunately all I can find is how to migrate to another machine when you have just installed Thunderbird. Unfortunately, I have already set up the Thunder on other machine [for the same e-mail address] and now the same adress has two different profiles - on the old machine and on the new one. Is there to way to merge old with new, as I cannot simply copy/paste it seems?

Thank you!

You can copy and paste, but follow some rules.

To get an identical copy of what is on the old computer put onto the new computer. I'm assuming on both computers you are using Windows OS and everything is in default location

1. Check: You need to be running exactly the same version of Thunderbird on both computers - this is important. 2. Exit Thunderbird on both computers - this is important.

On old computer..... 3. Access this location: C:\Users\<Windows user name>\AppData\Roaming folder. 4. Copy the 'Thunderbird' folder and paste into external device to aid transfer.

On new computer..... 3. Access this location: C:\Users\<Windows user name>\AppData\Roaming folder. 4. Delete the current default 'Thunderbird' folder which has the new profile. 5. Paste the copied 'Thunderbird' folder into the 'Roaming' folder. This replaces the one you deleted.

When you start up Thunderbird on new computer it will be an identical copy of what you had on the old computer.

Please note the 'Appdata' folder is a hidden folder, so you might need to make hidden files and folders visible. https://support.microsoft.com/en-us/windows/show-hidden-files-0320fe58-0117-fd59-6851-9b7f9840fdb2
