Hi Vaughn,
Although you can do that, all I have usually done is isolate IIS so that it nly accepts traffic from localhost as well as its actual IP address, as this cuts out comms to all nodes except for the SMP's own SMA.
If you did want to do this, you would need to target the ItemActive table I believe. Best approach would be to copy its contents into a temp table, set all 1 entries to 0, and then after the upgrade simply copy the contents from the temp table back to the modified table.
Scott.
