  • Depends on the number of mail domains/users/aliases, mailbox size, and other data needed to be migrated, the price may be different, there isn't a fixed price for migration service.

What Customers Are Saying ...

Shamim Mirzai,, 27 Jul 2015.

It’s such a pleasure to find a software product that “just works” and even more so when it’s creator backs it up with professional support. Zhang Huangbin is well versed in everything email related and has proved to us what a dedicated professional he is. At a difficult time for our company when our previous hosting provide let us down catastrophically, iRedMail and Zhang helped us get a new email system up and running in literally hours and get all our clients operational again with their email accounts. I have no hesitation in recommending both the iRedMail Pro software and Zhang’s help and support.

I would like to give my highest respect and recommendation for Mr. Zhang.

We've asked Mr. Zhang to develop a few iRedMail features for us (paid). We've worked with total collaboration. The features were ready as scheduled and he was very responsive to our comments and requests. The problems that were encountered during the development phase were fixed with a very high technical knowledge. We are more than satisfied with the results.

Again - I give my highest recommendation for Mr. Zhang and iRedMail as a solution.

Colin Warner, Jun 26, 2014. Migrated from Exim/OpenLDAP to iRedMail.

I would like to recommend iRedMail and Zhang Huangbin. We had a difficult migration to perform due to the age and lack of resources of our old mail server. We engaged Zhang to do the migration for us. Zhang was very responsive to any issues that arose and closely monitored the transfer of data which occurred over a period of 24 hours or more.

We received prompt remote support over the following days and he quickly resolved a number of unexpected issues that arose. Zhang communicated regularly during the first two weeks after installation to make sure we were happy with the new mail system, and was pro-active in identifying and fixing problems.

Zhang has excellent written English so there was no difficulty with communication during the whole process. I would highly recommend using Zhang's services to carry out a migration to iRedMail.

I ordered remote upgrade support by iRedMail to safely upgrade a production machine to the latest version and everything worked like charm :). Zhang Huangbin logged into the machine exactly at the requested time and informed me live about every single step he was about to do. Being logged in as well, i could follow everything he did and felt really safe. Everything worked so smoothly, that there was no service interruption, no angry users and not a single mail lost. Thanks again, it was well worth the money!
