Security upgrade from 4.6B to ECC6.0

Hello Experts,

I am going to perform security upgrade from 4.6B to ECC6.0. Below is my analysis in the system 4.6B.

Aaround 5000 Manual profiles and 2700 Roles are there in the system. Also 3000 custom t-codes & 180 custom objects are there. I don't have experience on Manual Profiles. Here is my questions.

1. Could you please let me know how to down load list of Manual profiles in the system?I checked in SUIM..here it's showing Manual profiles & profiles assigned in the roles.

2. How to check existing t-codes in manual profiles? I have checked in SUIM-->Transactions executable in profiles, but here it's not allowing to select multiple selection of profiles.

3.Also please let me how to check Org values & Objects in Manual profiles?

Please let me know if any tables or any other way to check the same.

For example in roles we have tables like AGR_TCODES, AGR_1251 & AGR_1252..kindly let know the same as Manual profiles.

Thanks in advance for your help.

Regards,

Sudhakar
