I've installed Thunderbird 38.2.0 on my newer Mac (OS 10.5.7). I've been running Thunderbird for years on my old Mac (OS 10.5.8) using Thunderbird 16.0.1. Love Thunderbird, but yes, i should have upgraded a long time ago ;-) The OS on the old Mac is too old to upgrade to the current version of Thunderbird. The new version of Thunderbird is running fine on my newer Mac. But i need to find a way to get my address book and my mail files from the old Mac to the new Mac. Please, please help! Claire Russell

I think the best approach is to copy your entire profile from the old computer to the new one.

Alternatively…

You could import messages from the old profile; I'd suggest using https://addons.mozilla.org/en-US/thunderbird/addon/importexporttools/

You could import address books from the old profile; you can copy abook.mab (Personal Address Book) and history.mab (Collected Addresses) directly. Other *.mab files can be copied over too, but may need to be imported, using https://nic-nac-project.org/~kaosmos/morecols-en.html

Thank you so much. I was able to copy both my old address book files and my old local folder files to the new version of Thunderbird. All is working and i'm a happy Thuderbirder again.
