Upgrading

This section is for users who are upgrading from a previous version of IMail Server. IMail Server is automatically installed in the same directory where you had the previous version or evaluation version. This directory should not be changed, moved, or renamed.

  1. Log on to Windows NT/2000 as System Administrator, or to an account with System Administrator privileges.
  2. Make sure the Windows NT/2000 Control Panel is closed, as well as all other applications.
  3. Back up the Windows NT/2000 registry key, 
    H_KEY_LOCAL_MACHINE\Software\Ipswitch\IMail\

    (Start regedit.exe, locate this key and select Export Registry File from the Registry menu.)

  4. Do one of the following:
    • If you purchased an IMail Server CD-ROM, insert the CD-ROM in a drive. Select Run from the File menu, and then enter the CD-ROM path followed by setup.exe.
    • If you downloaded IMail Server from the Internet, run the downloaded application, imailec.exe.

Note: It is strongly reccomended that you stop all IMail services and close the IMail Administrator interface before upgrading.

  1. Follow the prompts on your screen. If you have any questions, click the Help button, or press F1.
  2. If the installation program does not detect SSL keys on your computer, you will be asked whether or not you want to install default SSL keys. Here's how to decide:
    • If you already have a third-party SSL certificate, click No. After installing IMail Server, run the IMail SSL utility and follow the instructions in Help.
    • If you do NOT already have a third-party SSL certificate, but want to run the IMail web server using a "self-signed" SSL certificate, click Yes.
    • If you want to read more about SSL before making a decision, click No. You can install default keys later. For more information, see "Using Secure Sockets Layer (SSL)".
  3. Restart your system when the installation is completed.

Upgrading Using External Databases

When installing IMail Server v7.0 over an earlier version, in which one or more hosts use an external user database, new columns must be added to the database tables. This is due to additional user-level data which must be stored for use with the new Web Messaging and Web Calendaring features. The new columns must be added to the user table for each IMail Server host that uses an external database.

During the install, IMail Server will determine whether your system currently uses an external database. If the answer is yes, then a dialog is displayed giving you the three following options:

Note: If you click No and install anyway, be advised that IMail Server may not function correctly.

If a custom ODBC driver was used with a previous version of IMail Server, the driver must be modified to use the new columns. Source code for the basic ODBCUser.dll driver (tailored for SQL Server and Access) can be downloaded from the IMail Support Center:

Upgrading Web Messaging

If you have customized templates you want to continue using, refer to the "Upgrading Customized Templates Document"(Upgrade6to7.txt) for procedures to upgrade the old templates for use with IMail Server v7.0. This file is located in the [IMail Top Directory]\Web\New directory. See also the web messaging topic "Upgrading".

Re-Installing IMail Server to a Different Location

When re-installing IMail Server to a different location, the WEBDOCS value in imonitor.ini is not updated. This causes the up.gif and down.gif files in IMonitor to be missing on the Service Status page. IMonitor produces the WEBDOCS value, but does not know when a reinstall has occurred, or when a web directory has been moved. If you change the install location of IMail Server, you MUST update the WEBDOCS field in the imonitor.ini file to point to the new location so the GIFs will be loaded properly.
