Plan the upgrade process in advance to ensure both the full bene= fit from the latest Precise release and adherence to your schedules and nee= ds.
To ensure a quick and efficient upgrade, review the following sub-topics= before beginning the procedure:
Before planning the upgrade process, verify that:
Your existing Precise installation typically spans many servers. Because= the upgrade to the latest version of Precise is performed per server, you = should plan in advance the order in which you will upgrade all servers comp= rising your existing Precise installation.
If you are unable to upgrade all servers at the same time a= nd are updating only a few servers at once , review the impli= cations of a phased upgrade described below.
The order of the server upgrade is:
When starting the upgrade, select all the FocalPoints servers. You can a= dd additional servers for the upgrade once the FocalPoints servers are upgr= aded or as part of the FocalPoint upgrade. In which case the server upgrade= starts once the FocalPoint servers are completely upgraded.
If you are unable to upgrade all servers at the same time a= nd are updating only a few servers at once , the following li= mitations apply to your Precise system functionality:
The upgrade process does not require any downtime of the monitored techn= ologies.
The upgrade process involves downtime of the Precise product itself as d= escribed below.
When updating the servers with the Precise FocalPoints, the installed Pr= ecise performance monitoring system is not in operation. Once the Precise F= ramework upgrade is complete, Precise resumes all performance monitoring pr= ovided by the previous version of Precise.
The time required for updating a server with the Precise FocalPoints may= vary depending on:
In general, updating a server with a Precise FocalPoint is estim= ated at one hour. Updating a server with a FocalPoint is fastest w= hen application of the upgrade is performed using AdminPoint on the Main no= de server with the Precise FocalPoint, and the upgrade is located on storag= e providing good response time to that server.
If you have a federated Precise deployment, then when updating the serve= rs with the FocalPoint of the Main node, your entire Precise federated depl= oyment is inoperable for performance monitoring. When updating another node= 's servers with a FocalPoint, only that node is inoperable for performance = monitoring.
Precise agents do not collect performance data during an upgrade. The ti= me required to upgrade a server running Precise agents varies depending on = the technology type and the number of Precise agents on that server, as wel= l as the factors described above regarding updating the server with the Pre= cise FocalPoints. In general, updating a Precise agents server is e= stimated at 20 minutes.
Use the following checklist to verify that you are ready to upgrade Prec= ise to the latest version:

:tick: | Plan the Precise upgrade order according to Serv= er update order previously discussed. |
:tick: | Complete all planning according to this topic.= td> |
:tick: | Review the Precise Customer Support Portal (https://idera.secure.force.com/precise/) for the appropri= ate product upgrades. |
:tick: | Coordinate and convey the downtime associated wi= th this Precise product upgrade. |
