How to upgrade with the latest version and what is the difference

Version numbers

The Application version is always visible at the very top of the main application window. It consists of 4 numbers separated by dots, Example:, following the pattern below:


which mean the following:

  • [major] -The leftmost number or the first is called the major version. it rarely changes – only when significant features are introduced to the software.

  • [minor] - The second digit changes every time when we release a new version with planned improvements or any additional functionalities are added (see release notes).

  • [maintenance] - digit in the third position will change only when there is a software release that was not originally planned. This usually happens when an important bugfix must be added and cannot wait for the next minor version change.

  • [build] - A build is a set of changes to the software or its minor update, UI changes, fixes, or improve it. This includes fixing security vulnerabilities and other bugs, with such builds usually being called bugfixes or bug fixes, and improving the functionality, usability or performance.

How to Upgrade

  1. Download the installer from the download page onto the machine where migration software is installed.

  2. Launch the downloaded installer and install the program.

    Warning: If the application is running, it will be terminated by the installer, and you will have to resume them manually after the upgrade.

  3. If you have installed the program on more machines in your environment, perform the upgrade on each machine where the program is installed.

  4. After the upgrade process is complete, you can launch the program. All of your settings are retained, but you need to resume the migration manually.

I had tried many applications for my few hundred mailboxes migration. But none of the application could be able to complete more than a couple of mailboxes migration. When I had contacted they started reporting that it is due to Office 365 throttling issue. Later out of curiosity I have tried EdbMails Office 365 migration with basic plan. EdbMails is the first application completed my 20 mailboxes migration successfully. Upgraded my migration plan and could be able to migrate all my Office 365 mailboxes without any issues. Last week did a re-migration and EdbMails is the only application does a perfect incremental migration without creating a single duplicate items on re-migration. Thanks to EdbMails, it is a hassle-free Office 365 migration software :)
