Upgrading to IT Resource Management
3.3
Upgrading your existing software deployment to SAS IT Resource Management 3.3
enables you to update your software and configuration yet retain your existing work. In
other words, you can replace (or overlay) your current version of SAS IT Resource
Management with SAS IT Resource Management 3.3. With this process, you are not
moving content from server A to server B. Instead, you are modifying the content in
place.
This function is helpful if your site has a limited supply of hardware to use for installing
new releases of SAS software. However, using this functionality prevents you from
validating the new software by running it in parallel with the older software that is in
production.
CAUTION! The upgrade process cannot be reversed. Once you upgrade your
software, you cannot revert to the previous version. You can restore the older system
from backups if you have created the necessary backups.
This functionality is available only when multiple product versions exist within the same
SAS release.
