Downgrading from 141.0 on mac to 128.12.0 on fedora
I recently had a hardware crash on my fedora machine and transferred my thunderbird backup to my mac. I have a new fedora machine and want to transfer my thunderbird profile from the mac to the fedora machine. The problem is that Fedora is currently at version 128.12.0 and the mac is currently at version 141.0.
In response to a previous question https://support.mozilla.org/en-US/questions/1513367 I got a suggestion (which I have not been able to make work). 'if you Exit Thunderbird and access profile name folder, then delete the 'compatibility.ini' file, you should be able to use the profile on an older version.'
Here is the revelant directories on the mac
``` bradbell>ls Library/Thunderbird/Profiles y0mvyr8l.default
bradbell>cat Library/Thunderbird/profiles.ini [General] StartWithLastProfile=1
[Profile0] Name=default IsRelative=1 Path=Profiles/y0mvyr8l.default
bradbell>ls Library/Thunderbird/Profiles/y0mvyr8l.default/ | grep compatibility compatibility.ini ```
I think I should put y0mvyr8l.default in $HOME/.thunderbird but I am not sure what should I change ?

Hi, I just did the following:
- Make a backup of the whole profile folder (just in case) on 128.13.0esr (64-bit) Fedora - Created a new profile on Fedora's Thunderbird (thunderbird -p) on another machine running 142.0b4 - Moved the content of the old folder to the new profile folder - Started the 142 with the -p newprofile - All worked fine with one small exception of a non-saved username of a calendar integration
OH, I just saw that you have the case of downgrading. Let me try this, instead!
I did the same from: 142.0b4 > 128.13.0esr and didn't experienced any problems. Do a backup and try!

Brad, what were your results?
When I try to import (in 128.13) the Thunderbird backup zip (exported by 142.0) I get the message:
'The selected ZIP file is larger than 2GB. Please extract if first and the import from the extracted folder instead.'
In fedora, when I try to unzip the file I get
Downloads>unzip Thunderbird_profile_backup.zip Archive: Thunderbird_profile_backup.zip warning [Thunderbird_profile_backup.zip]: 4294967296 extra bytes at beginning or within zipfile
(attempting to process anyway)
file #1: bad zipfile offset (local header sig): 4294967296
(attempting to re-compensate) extracting: y0mvyr8l.default/abook.v2.sqlite
error: not enough memory for bomb detection

I tried the following:
1. Using Thunderbird 142.0 (on my Mac) and the export tool create Thunderbird_profile_backup.zip
2. scp the zip file to my Fedora machine.
3. Using the Thuderbird 128 import tool try to import from a backed up profile (In Fedora). I got the following message: The selected zip file is larger than 2GB. Please extract it first, then import from the extracted file instead.
I also get errors if I try to unzip the backup on the original machine (the mac).
The zip format seems to be very inefficient and is taking up 8.2GB.
If, on the Mac, I do use tar -czf Profiles.tgz Profiles I get a file of about 3.6GB. If I copy it to my fedora machine then tar -xzf Profiles.tgz
The use the import tool on Fedora to inport Profiles/y0mvyr8l.default
It seems to work, but I think it runs out of memory somewhere during the import and a lot of things are missing.
I suspect that I am going to have to delete a lot of the information on the Mac before I will be able to move it ?
