Integration of single SF to Dual ECC via HCI/PI
We have a scenario where there are 2 ECC systems running for 2 different business (companies) merged later but not merged into single ECC.
ECC1 is running on HANA DB and ECC2 is runnning on non HANA DB.
Now, requirement is to use single Successfactor Cloud System for both ECC systems and integration to be done through single HCI or PI.
Could you please advise and elaborate on this.
1. Can single SF integrate with ECCs.
2. HCI or PI, what is best tool with respect to long term solution, cost, scalibility, new contents and mappings, flexibility etc as there is now PI already running.
3. Pros and Cons of both HCI and PI for integration SF.
4. Challenges in integrating single SF with 2 ECCs with respect DB and any other factors you want to highlight.
