You must uninstall any previous versions of P6 before upgrading to 15.1.
Cautions:
Before upgrading P6, you should upgrade the P6 EPPM database to 15.1. See the Upgrading and Configuring P6 EPPM or Manually Upgrading the P6 EPPM Database guide for details on how to upgrade your database and for information on potential impact areas to your environment. For the full list of tested configurations for P6, go to the \Documentation\<language>\Tested_Configurations folder of the P6 EPPM physical media or download.
If you are a current Apache JackRabbit user and want to upgrade to P6 EPPM 15.1, JackRabbit documents data will not migrate automatically. Refer to My Oracle Support's Knowledge Articles for information on manually migrating JackRabbit documents to Oracle Universal Content Management. Oracle recommends that you migrate the data before upgrading to 15.1.
If you are a current jBPM user and want to upgrade to P6 EPPM R15.1, workflows and reviews data will not be available. You should close all workflows and reviews that are in progress before upgrading to P6 EPPM 15.1. You cannot migrate any of this data to 15.1.
Starting with P6 EPPM R8, all recurring job service functions are hosted by P6. Due to this change, after upgrading to P6 EPPM R8 or later, you must configure Scheduled Services settings in the Primavera P6 Administrator to use this functionality. Also, if you're upgrading from version 7.0 or earlier, you must RESUMMARIZE ALL PROJECTS to accurately reflect your summary data. See the P6 EPPM Post Installation Administrator's Guide for information on Scheduled Services and configuring separate servers for job services.
Tips
For security reasons, Oracle strongly recommends that you replace the default Admin Superuser (admin) immediately after a manual database installation or an upgrade from P6 version 7.0 and earlier. See information about the Admin Superuser in the P6 EPPM Post Installation Administrator's Guide.
P6 EPPM does not support Summary-Only projects. During the P6 EPPM database upgrade, existing Summary-Only projects convert to standard projects, but lose all summary data. You can import the summary project from Microsoft Project into the converted blank project, then summarize the data. See the P6 Professional Help or the P6 Help.
During the upgrade to P6 EPPM 15.1, some P6 Activity Views settings will reset. After the upgrade, use the Customize Detail Windows feature to modify the settings that should appear for each view. See the P6 Help for information on how to edit Activity Views.
Starting with P6 EPPM R8, P6 saves filter definitions globally. Filters still work for Activity Views, but all standard filter assignments reset during the upgrade. Due to this change, views that had Standard Filters applied will show all activities after the upgrade. Reapply filters after the upgrade finishes. See the P6 Help for information on how to edit Activity Views.
