I'm trying to copy a v147 windows profile to a v140 esr linux profile without re-downloading the imap messages.

I'm trying to move from Windows to Linux without downloading all my imap messages again. What I've tried: 1. Install tbird on Linux, create new profile. 2. Close tbird. 3. Using Linux file manager, 

 - delete contents of new profile folder
 - copy contents of old profile folder into new folder
 - delete Compatibility.ini in the copy

4. Open tbird with -p (profile manager)

I've tried twice with different results. The first time at step 4 I started offline. Thunderbird opened will all my previous tabs open, except that all the internet tabs reported connection failure - as expected. Under account settings, both local folders and my gmail account reported the correct (new, linux) path. When I went online and completed the gmail OAuth dialog thunderbird reported an inbox summary folder error, and deleted all the imap mbox files. I closed and restarted tbird- which failed with a crash dump. the terminal window reported successful minidump creation- the file manager showed the minidump file at zero size.

I repeated the process (recreating the original unmodified profile). This time at step 4 I started online, and tbird never opened- it generated the crash dump immediately.

Two questions: 1. Is it possible to transfer an imap profile and avoid re-downloading all the old messages? 2. What am I doing wrong that I'm getting the crash dumps?

Is it possible to transfer an imap profile and avoid re-downloading all the old messages?
Transferring a profile is possible, but there may be some issues. See https://kb.mozillazine.org/Move_to_a_new_PC#Moving_from_Windows_to_OSX_or_Linux

If the ESR version number you are changing to is lower (older) than the release version number you have been using, then you must use --allow-downgrade parameter for the first startup, to override downgrade protection. Note, files from a newer version are not guaranteed to work in an older version. However, I wouldn't expect any problems related to an IMAP account. See https://support.mozilla.org/en-US/kb/thunderbird-release

Wrt the 'not re-downloading all the old messages' part, simply turn off IMAP synchronization. https://support.mozilla.org/kb/imap-synchronization

Note, with IMAP synchronization turned off you can't create local backups of your email archive.

The portable version is provided by PortableApps.com, so you should check with them about your crashes. You may want to try using the current release version from https://www.thunderbird.net/thunderbird/all/
