In my old Suite mailbox, "All Mail" shows 156,912 messages.  I exported them with GYB.

Using the closest thing I can find to count the message on disk shows 161,956:

     findstr /s /B "From " *.* | find /v "" /c

(it's counting "From:" lines, too, even though I specified a space in the pattern)

When I went to import them, it showed a progress bar of "X of 151,710", so it seems that I've already lost 4% of the messages.

After the import finished (about 3 days!), the new gmail "All Mail" shows 56,646 messages, so I've lost 64% of the original email.

I'm using the restore command from the doc:

    gyb --email newad...@gmail.com --action restore --local-folder GYB-GMail-Bac...@gmail.com

Any ideas on how to get a complete restore, and perhaps do it in less time?

No, I didn't receive any pointers on how to use the tool successfully or whether it taking 3 days was to be expected.

Did you ever figure this out?  I did a backup from one account, and GYB showed over 60k messages (confirmed by the count in All Mail).  I did a restore, and it looked like that's what it was restoring.  All Mail in the new account says 35k messages...

For what it's worth, there can be a discrepancy in number of messages due to conversation threading settings, etc. 

Depending on invalid headers, size of message/attachment too big, or other random errors, messages can get skipped, but in general GYB has been very reliable and extremely useful for me. 

I never really pay attention to message count, but going by mailbox/export sizes, large ones can definitely take a couple days. Plenty of times I've told someone I'm kicking it off Friday night, we can check back after the weekend etc.

Good luck!
