When run in interactive mode, the Meridian setup program will detect a previous version of Meridian, and offer to upgrade the previous installation.
Before proceeding with any upgrade, carefully consider the following points.
-
You must install the upgrade first and at least on the Meridian application server and eventually all client computers.
-
Older versions of the client applications will continue to work with the upgraded server, but this should be considered only a temporary measure until all client computers can be properly upgraded. Upgrade the client computers as soon as practical.
Accruent does not provide technical support for production environments in which different versions of Meridian Enterprise software are used on server and client computers.
-
The software will be installed in the existing folder structure. If the default folder names for the new software are different from the existing folders, the default folder names will not be used, which could make troubleshooting more difficult.
-
After the upgrade process has completed, the setup program might prompt to restart the computer so that files that are in use can be deleted. If you choose to upgrade Meridian client computers automatically and configure the setup so that an automatic restart is not executed, the software will not function correctly until the computer has been restarted. After the computer has restarted, always log on to Windows with an account that has at least the same security privileges as the account that started the upgrade.
We highly recommend that you:
-
Use the Server Installation Checklist to guide you through the upgrade process and complete all of the items in the Upgrade column that apply to your environment.
-
Perform and troubleshoot the upgrade on a test server with a current copy of your production environment first before attempting to upgrade the production environment.
-
Perform comprehensive user acceptance testing in a test environment before deploying the upgrade to the production environment.
