Prerequisites for the upgrade
Before planning the update upgrade process, verify that:
- Your system meets all minimum requirements updating to the latest version as per the Precise Minimum Requirements for Installation Guide.
- The Precise installation that you want to update upgrade is fully updated upgraded to the required previous version. If some agents are not yet updated upgraded to the required previous version, complete the update upgrade to that version prior to attempting to update upgrade to the latest version.
- Free disk space exists on the servers where the required previous version is installed. Minimum requirements include:
- 0.5GB on each server containing Precise Agents
- 2.5 GB on the Precise Framework server
- 0.5GB free disk space exists on the client server from which you want to execute the updateupgrade.
- Precise for Tuxedo is not installed in your environment.

upgrade order
Your existing Precise installation typically spans many servers. Because the update upgrade to the latest version of Precise is performed per server, you should plan in advance the order in which you will update upgrade all servers comprising your existing Precise installation.
If you are unable to update upgrade all servers at the same time and are updating only a few servers at once, review the implications described in Implications of a phased update to the latest version of Precise.
The order of the server update upgrade is:
- Update Upgrade all FocalPoint servers.
- Update Upgrade all other servers.
When starting the updateupgrade, select all the FocalPoints servers. You can add additional servers for the update upgrade once the FocalPoints servers are updated upgraded or as part of the FocalPoint updateupgrade. In which case the server update upgrade starts once the FocalPoint servers are completely updated.

upgrade to the latest version of Precise
If you are unable to update upgrade all servers at the same time and are updating only a few servers at once, the following limitations apply to your Precise system functionality:
- After starting an updateupgrade, you cannot install, edit, or uninstall instances on a server until the update upgrade is complete.
- For installed Web and J2EE clusters, new instances are not installed until the cluster's servers are updatedupgraded.
- If you created a Template Listener as part of you server's image, new Template Listener installations fail after the updateupgrade. You must recreate the Template Listener once the framework update upgrade is complete.

Downtime

of the monitored technologies
The update upgrade process does not require any downtime of the monitored technologies.

...
Downtime of the Precise product
The update upgrade process involves downtime of the Precise product itself as described below.
FocalPoints
When updating the servers with the Precise FocalPoints, the installed Precise performance monitoring system is not in operation. Once the Precise Framework update upgrade is complete, Precise resumes all performance monitoring provided by the previous version of Precise.
...
- the strength of the server with the FocalPoint
- the strength of the server where you are using AdminPoint to apply the updateupgrade
- the file transfer speed
- the amount of Precise technologies monitored by Precise
- the time it takes to perform post-application action items
In general, updating a server with a Precise FocalPoint is estimated at one hour. Updating a server with a FocalPoint is fastest when application of the update upgrade is performed using AdminPoint on the Main node server with the Precise FocalPoint, and the update upgrade is located on storage providing good response time to that server.
If you have a federated Precise deployment, then when updating the servers with the FocalPoint of the Main node, your entire Precise federated deployment is inoperable for performance monitoring. When updating another node's servers with a FocalPoint, only that node is inoperable for performance monitoring.
Non-FocalPoint agents
Precise agents do not collect performance data during an updateupgrade. The time required to update upgrade a server running Precise agents varies depending on the technology type and the number of Precise agents on that server, as well as the factors described above regarding updating the server with the Precise FocalPoints. In general, updating a Precise agents server is estimated at 20 minutes.
