The order of the server update is:
...
When starting the update, you must select all the FocalPoints servers. You can add additional servers for the update later (once the FocalPoints servers are updated), or as part of the FocalPoint update (in this case the server update will start once the FocalPoint servers are completely updated).

If you are not updating all servers at once, but are updating a few servers at a time, the following limitations will apply to your Precise system functionality:
- After an update has started, a server that has not fully completed the update cannot have instances installed, edited, or uninstalled.
- For installed Web and J2EE Clusters, new instances will not be installed until the cluster's servers are updated.
- If you have created a Template Listener as part of you server’s image, new Template Listener installations will fail after the update. You must recreate the Template Listener once the framework update has been completed.

In general, updating a Precise agents server is estimated at 20 minutes.
