We have question in Ariba upgrade strategy. If we are having CI6 in Test and Production environments and now want to upgrade with CI7 version.
1. How much time needed to upgrade from CI6 to CI7 ( one version to another version)
2. If Test environment is on CI7 due to upgrade and production environment is running on CI6 as upgrade not yet deployed in Production then how we should handle production issues. As test environment is upgraded but Production environment is not yet upgraded.
3. What should be testing strategy during CI version upgrade
