SystemMen - How to migrate mail data from Google GSuite to Zimbra? This article will guide you to do that.
There are many tutorials on how to migrate data from Zimbra to GSuite or from Mdaemon to GSuite. But today, I have the opposite situation, I have to migrate mail data from Gsuite to Zimbra.
First of all, I want to thank this article. In fact, this is the first time I migrated from GSuite to Zimbra.
In the article that I refer to, the author mentioned two ways to migrate mail data. I only use the first method, migrate each account. You can try the other way.
This article I want to share my experience with you.
Prepare steps before migrate mail data
We need to prepare something before we can migrate mail data for a company of about 50 or 100 users or more.
Prepare on Zimbra server
First and of course, you need to create new accounts on zimbra system, to prepare for migrating mail data.
Note: You should set a password of moderate difficulty, do not contain special characters, should only include letters and numbers, it will help you limit errors when executing sync command. You can change the passwords of accounts to become harder after migrate is finished.
Login to Zimbra’s admin window and go to Configure -> Global Settings. Next, do the following 2 things.
1. Firstly, you move to IMAP section and select Enable clear text login.
2. Secondly, go to General Information and enter the number 25600 in the Maximum size of a file uploaded from the desktop (KB). Why, Zimbra default only allows 10MB while GSuite allows 25MB.
Therefore, when migrating data from GSuite to Zimbra, we need to edit the file size to the same.
And now, ssh to the Zimbra server and type the following command to install imapsync.
# yum install -y epel-release && yum install -y imapsync
Prepare on Gsuite admin account
After you have finished preparing on the Zimbra server, you now need to login to your Gsuite administrator account.
You go to Admin console -> Security -> Basic settings. Choose Enforce access to less secure apps for all users.
During the migrate of mail data, I encountered the most error that I could not access the gsuite mail account from the imapsync command.
This has 2 factors, you should test login in the browser to make sure you can access your gsuite mail account.
- First reason: user activates 2-step authentication by phone. You can use Gsuite administration to turn it off.
- The second reason: you need to make an access on the browser from a censored IP, preferably from your office.
Note: To facilitate migrate data, you should reset all account passwords to a single password. Password should only include letters and numbers, to limit errors when executing sync command
If you set a password with many special characters, you may encounter the following error. For example, the password is abc123)(*.
bash: syntax error near unexpected token `)'
This may sound unreasonable, but you must do so. Because you cannot migrate the password from Gsuite to the Zimbra mail system. You can inform the user of the company and then change the password for each person after completion migrate.
Use Imapsync to migrate mail data
After you have prepared, we will now start migrating.
You can test whether migrate is successful by running the following command with the first few accounts.
[root@mail ~]# imapsync --host1 imap.gmail.com --user1 test@yourdomain.com --password1 Abc@123 --host2 mail.yourdomain.com --user2 test@yourdomain.com --password2 Abc@456 --syncinternaldates --ssl1 -ssl2 --noauthmd5 --split1 100 --split2 100 --exclude All Mail --useheader 'Message-Id' --dry --justfolders
The command with option --dry --justfolders will perform a check on migrate but not sync data.
Full test process look like this.
[root@mail ~]# imapsync --host1 imap.gmail.com --user1 test@yourdomain.com --password1 Abc@123 --host2 mail.yourdomain.com --user2 test@yourdomain.com --password2 Abc@456 --syncinternaldates --ssl1 -ssl2 --noauthmd5 --split1 100 --split2 100 --exclude All Mail --useheader 'Message-Id' --dry --justfolders Transfer started at Thu Jun 6 15:39:00 2019 PID is 901 Log file is LOG_imapsync/2019_06_06_15_39_00_test@yourdomain.com.txt ( to change it, use --logfile path ; or use --nolog to turn off logging ) $RCSfile: imapsync,v $ $Revision: 1.727 $ $Date: 2016/08/19 10:30:36 $ Here is a [linux] system (Linux mail.yourdomain.com 3.10.0-957.12.2.el7.x86_64 #1 SMP Tue May 14 21:24:32 UTC 2019 x86_64) with Perl 5.16.3 Mail::IMAPClient 3.37 Command line used: /usr/bin/imapsync --host1 imap.gmail.com --user1 test@yourdomain.com --password1 MASKED --host2 mail.yourdomain.com --user2 test@yourdomain.com --password2 MASKED --syncinternaldates --ssl1 -ssl2 --noauthmd5 --split1 100 --split2 100 --exclude All Mail --useheader Message-Id --dry --justfolders Temp directory is /tmp ( to change it use --tmpdir dirpath ) PID file is /tmp/imapsync.pid ( to change it use --pidfile filepath ; to avoid it use --pidfile "" ) Wrinting my PID 901 in /tmp/imapsync.pid Modules version list: Mail::IMAPClient 3.37 IO::Socket 1.34 IO::Socket::INET 1.33 IO::Socket::INET6 2.69 IO::Socket::SSL 1.94 Net::SSLeay 1.55 Compress::Zlib 2.061 Digest::MD5 2.52 Digest::HMAC_MD5 1.01 Digest::HMAC_SHA1 1.03 Term::ReadKey 2.30 File::Spec 3.40 Time::HiRes 1.9725 Unicode::String 2.09 IO::Tee 0.64 File::Copy::Recursive 0.38 Authen::NTLM 1.09 URI::Escape 3.31 Data::Uniqid 0.12 JSON 2.59 JSON::WebToken 0.10 Crypt::OpenSSL::RSA 0.28 LWP ?

Conclusion
This article, I tried to share my experience in detail as possible. The imapsync command only has one command, you only need to replace the username and password for each account and sync one by one. However, in the process of implementation, you may encounter things that I have encountered. Hope, this article helps you.
