If you are only interested in migrating the configuration data and none of the history, follow the instructions on “Migrate ACM Configuration to a New Server” instead.
Regarding SQL Replication:
If you are using SQL redundancy and you are replicating all objects, you only need to update the primary database and SQL replication will take care of updating all redundant servers.
If you are only replicating a few objects you will need to disable replication, update the primary database and then re-do Step 6 for each subscriber database. After all databases have been updated, then you may reenable replication.
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: Copy the database to the new server
Copy the .bak file you created in Step 2 to the correct location on the new server. The default backup location depends upon the version of SQL installed.
Step 4: Restore the database on the new server
To restore the database on the new server in SSMS, right-click on the databases folder and select “Restore Database”.
Select “Device” and click on the ellipsis next to the device field.
Click “Add”:
Navigate to the location in Step 3.
Select the database that you would like to restore and complete the prompts.
Step 5: Update the ACM Monitor Database Connection
Open ACM Monitor, select “Database” and then click the “Manage Database” button.
On the ACM Database Connection form, update the configuration settings.
If you need to upgrade the database, move to step 6, otherwise click “OK” and move to step 7.
Step 6: Upgrade the ACM Database
If you need to upgrade the ACM database after migrating it to the new server, click the “Create/Update Database” button.
The database wizard will open using the connection settings you just entered. If this user has adequate database server permissions, click “Next”, otherwise change the user to one with permission to modify the database and then click “Next”.
Select Update existing database and click “Next”
The following form loads with the already saved values - the same as are seen in the $Server object. Change them if you wish to and then click “Next”.
Click “Finish” to upgrade the database.
When it reports success, click “Done”.
