How to downgrade MailEnable


How to downgrade:

- Professional to Standard Edition

- Enterprise to Professional or Standard

- Enterprise Premium to Enterprise, Professional or Standard


NOTE: If downgrading from Enterprise Edition, ensure that it is configured to use Tab Delimited Files for configuration. This would be the case unless you explicitly configured MailEnable to use Microsoft SQL Server or MySQL for its configuration storage. If you are using a database, you can use the provider migration utility to move this information into the Tab Delimited File format. For more information please see the Enterprise Edition Manual on 'How to use the Provider Migration Utility'.

Before downgrading MailEnable, make sure you stop all the mail services, including webmail, and make a backup of the MailEnable installation. If you don't have any backup process then at least make a copy of the MailEnable Config and Postoffices directories to an alternate location. The paths for the Config and Postoffices directory can be obtained through the MailEnable Diagnostic Report.

  • From the Windows Control Panel's Add/Remove Programs, uninstall Enterprise or Professional Edition (whichever one is installed).
  • Install the edition of MailEnable that you wish to downgrade to, using the same paths and options that had been used on the previous installation.
  • Ensure that the IME_ADMIN account has permissions over the CONFIG and Postoffices directories by running the following commands from the Windows command prompt:

    CACLS "C:\Program Files (x86)\Mail Enable\Config" /t /e /g IME_ADMIN:F

    CACLS "C:\Program Files (x86)\Mail Enable\Config" /t /e /g IME_SYSTEM:F

    CACLS "C:\Program Files (x86)\Mail Enable\Postoffices" /t /e /g IME_ADMIN:F

    CACLS "C:\Program Files (x86)\Mail Enable\Postoffices" /t /e /g IME_STORE_GROUP:F

NOTE: The default installation paths are used in the above examples, so you would change these if you have installed MailEnable to a different path.
