Use the following steps to upgrade an existing ACM in place.
Step 1: “Freeze” the existing ACM server:
There is no feature in ACM to do this, so the responsibility lies on the user to prevent any changes being made to the database during the migration period. To do this you must:
Disconnect all HMI’s and OPC Clients from ACM to prevent asiData from being restarted
Disable all ACM services in the ACM Monitor on the Status tab.
Step 2: Back up the ACM SQL database:
Depending on the size of your database, this step may take a while to complete. To back up your database:
Open SSMS
Right-click the ACM database you plan to upgrade
Select “Tasks-> Back Up”
Unless the destination file you wish to back up to is already listed, “Remove” any you don’t wish to use, and click “Add” to add the new one.
Step 3: Upgrade ACM
The installer references the asiDATA.ini file for the saved database information. If a connection to the database can be made, the installer will examine the ACM database version and prompt for permission to update the database if needed. You can use the installer to update your current database or you can choose to update your ACM database manually later using ACM Monitor.
If upgrading to ACM 8.2.1 or later, unless otherwise specified, replication does not need to be disabled to upgrade the ACM database.
Step 4: Upgrade Redundant ACM Servers
If you have a redundant ACM server, perform step 3 above on all redundant nodes.
Step 5: Reconfigure SQL Replication
If you had to turn off replication or remove any articles of replication, you can reconfigure it now.
