This chapter describes the Upgrade in Place, which upgrades an environment to a later version and/or maintenance level with close to zero downtime and minimal risk. This is accomplished by maintaining the same software library names and database files. The upgrade also provides a process for falling back to the previous software level, provided that the compatibility mode has not yet been changed.
Uprade to version 9.0.21 using the Upgrade in Place process is supported in product versions 9.0.18 and later. To enable Upgrade in Place, you must first APPLY the pre-requisite PTF PG06480 (WI10163) (and pre-requisites) to the environment.
After a successful Upgrade in Place, if you have multiple IOA environments at the same INCONTROL software level that are non-SMP/E- managed and have no ICE, you can perform a Multisystem Upgrade to upgrade those IOA environments.
IMPORTANT: The following considerations MUST be taken into account before the upgrade process begins:
Step 3.2 - Set Compatibility Mode enables changing the compatibility mode to the upgraded level. No INCONTROL address spaces may be active during this step in order to avoid working in mixed compatibility modes.
If Control-M/Enterprise Manager is installed at your site and connected to this environment, consider upgrading it to the new level prior to performing Step 3.2 - Set Compatibility Mode. Otherwise, its compatibility mode must not be changed, and the latest features will not be available.
