I have been busy recently, but I am also very full. After two months of upgrading, the system has been upgraded from 4.7 to ecc6.0 sr3. in the past two months, I have paid a lot, but I have also gained a lot. Let's sum up my experience:
1. Never consider SAP upgrade as a Windows upgrade, and it is not as easy as an SP upgrade!
2. Be prepared to fight hard, and there will be various troubles during the upgrade process!
3. at ordinary times, the knowledge reserve is very important. During the upgrade, it is a task that tests the overall basis capabilities. It is difficult to complete the upgrade without sufficient knowledge preparation!
4. upgrading is actually a project and cannot be considered as a work that can be done by one person. Although I am doing this upgrade, I was assisted by the Guiyang brothers, so that the project can continue!
5. Upgrading a project is a great test of your mind. You must have a strong will. Otherwise, it is easy to give up on the road!
6. the upgrade guide of SAP is quite tedious. If you are a friend who has no experience upgrading, you are advised to read it several times based on the upgrade step to streamline your thinking and implement it again. Otherwise, even after the upgrade is successful, you don't know what you are doing, so you have to say it's sad!
7. Can I solve the problem after careful analysis? If you are not sure you can solve the problem, please send a message to consult sap support. Do not search for posts on the forum directly by Google. others' replies will not be responsible for your issue!
We hope to share our experience with you! You are also welcome to leave a message for discussion!
