Friends,
We are currently on BW7.0 and have a DEV, TEST1, TEST2, QA1, QA2 and PROD. We would like to upgrade to BW7.4. Can you please clarify the following:
1. Is a direct upgrade to BW7.4 supported from BW7.0. And which SP is the most stable on BW7.4. We are looking at BW on HANA in future.
2. We would like to do the upgrade with no impact to business and would like to explore the side car approach. Is there any documentation available to perform a side car approach with no impact to business. How will dual system delta be handled if a side car is implemented.
3. If we went with a BIG Bang approach what is the average down time required. Our BW system is 5 TB in size.
4. What should be the Transport path during the upgrade process to handle enhancements and break fix. Any documentation ?
5. What is the minimum time in which this upgrade can be completed end to end.
6. What are the major issues to look out for with this upgrade and any specific compatibility issues.
7. Any documentation or quick guide to plan this upgrade.
8. Is there any dependencies on the ECC Version. We are on ECC6.0 EHP03.
Any inputs will be very much appreciated.
Thanks,
sa
