Import of GMAIL using labels

Import of GMAIL using labels

I have a Gmail account with close to 100,000 emails and don't want to migrate all of them to my new Zoho Account.

I thought I could do so by:
  • Making a Label called Zoho
  • Adding all the emails I wanted to that Label (5,000 or so)
  • Using the Add Account and Exclude Folder listing all of the folders and labels that were NOT called Zoho
That seems to be hanging (45 minutes still says 'Adding Members')

If I archive this same email account with Gmail can I import that zip file/archive? Or is the format wrong? If I can't import then is there a way to use the lablel solution listed above in a way that will work?
