IBM Cognos releases new features, bug fixes and more several times of year as Cognos Upgrades. It is important for UCSD to upgrade their Cognos environments at least once a year, depending on stability and contents of each upgrade, in order to take advantage of the new capabilities and keep current with security features. ITS-BIA will communicate upgrade contents and schedules via email to the cognos-developer-l@ucsd.edu mail list and via Team to the Teams Cognos Community of Practice.
Cognos developer report testing at the beginning of the upgrade is critical to a timely and successful upgrade.
All upgrades for Cognos Analytics occur in place. High level, the strategy for all upgrades is:
- ITS-BIA will review the upgrade in our sandbox prior to planning an upgrade of DEV
- Perform upgrades of the DEV environment on the weekend before the 3rd week of a month as this is generally the quietest period of the month for most teams.
- Allow one (1) week for review of the upgrade in the DEV environment.
- Report developers are expected to review new features and test their existing content for any issues.
- Issues should be reported to busintel@ucsd.edu with the subject "Cognos Upgrade"
- At the end of the week a GO/ROLLBACK determination will be made.
- GO – the upgrade is applied to QA over the weekend following the DEV upgrade (Upgrade is NOT applied to PROD at this time).
- ROLLBACK – the upgrade is rolled back from DEV
- During the one week period where DEV has been upgraded and QA / PROD have not, all teams will be in a “code freeze” in that no migrations from DEV can occur.
- Allow two (2) weeks for review of the upgrade in the QA environment.
- At the end of the week a GO/ROLLBACK determination will be made.
- GO – the upgrade is applied to PROD over the weekend following the QA upgrade.
- ROLLBACK – the upgrade is rolled back from DEV and QA.
- During the one week period where DEV and QA have been upgraded and PROD has not, all teams will be in a “code freeze” in that no migrations to PROD can occur. Migrations from DEV to QA may be conducted.
- Upgrade the PROD environment.
- Based on GO determination from both Cognos QA and Cognos DEV environments based directly on your feedback.
