GMail to cPanel email migrations?

I currently have a domain using GMail and I would like to completely migrate it to cPanel.

By that I mean, I wish all the emails currently in GMail to be migrated into the cPanel respective mail account.

Alias, forwards and alike are not a big deal, as I can generate it later. What matters are the emails there stored.

My question is, if I set cPanel as Backup Mail, will the emails including old ones get copied or would I have to completely set cPanel as the mail service and use something like imapsync to get the emails?

Will imapsync properly save the emails in a format compatible with cPanel?

From my search I have this 2 threads in sight:

• https://forums.cpanel.net/threads/migrating-from-gmail-to-cpanel.337481/
• https://forums.cpanel.net/threads/migrating-email-accounts-redirects-from-cpanel-on-a-shared-server-to-a-vps.253751/

Those however don't list any walk-through or anything other than the tools to achieve this.

Since I never did this sort of migration from GMail to cPanel I would love to hear from those who have done it before or from a cPanel staff?

Since those threads are rather old as well perhaps there are different methods, tools or even built-in within cPanel to achieve this?

Code:

Thanks for the answer @Infopro and @twhiting9275, since it had way too many folders and messages over 200k mails among several folders(on a single email account, god knows about the other emails), I opted to use imapsync from the console.

It went rather fast and ended up in a few hours, I am yet to verify the mails and if it all went well, but aside from being able to run it automated, there are several configuration options that can be used, including folder renaming, conversion and exclusion.

And of course, I was using a test account, once I confirm everything went as expected I will re-run for the real thing.

Only down side of it was that i had to turn on insecure logins on the google options but its not the end of the world.

 

So, I went to check the mails and compare against the real account and I have to say imapsync did a really nice job, so nice I would like to suggest it to be implement to cPanel migration options for accounts that are not under cPanel.

Not only it copied all the emails, but it reproduced all the folders and properly place the mails under each folder just like it was on GMail, I did remove some folders, like starred and/or renamed some folders, as to avoid having All Mails and Inbox and that is all done with the switches from imapsync which is done automatically after it done gathering the mails.

It does take awhile to get all the mails if you have tons of it but it works wonderfully and no slave work.

How fast does Outlook copy folders on a per mail basis?

 

Yes, that is basically what I was wondering. Like it will probably have a rate per message and an avg, I will probably that it later with Outlook so I can compare the speed, despite that being able to do it unattended is always the best .

As for opening a request, I found this one:
Migrate IMAP mailbox to cPanel

So I am not really sure I should open a new one or what to add to it.

It seems to have some votes despite that so I will leave it to you.
