Hi Experts
We are upgrading sap hcm from Ecc 5.0 to Ecc 6.0.
We also upgrading portal from EP 6.0 to EP 7.0.
We have 5 customized PCRs in previous verson.
I have some doubts
1) Do i need to take any precautions before doing upgrade ? If Yes What are they ?
2) Does this upgrade have any impact on my PCRs? If yes what kind of impact for example: in tables or PDF document etc?
3) is there any other input regarding both upgrades ?
please help
