Hi Dignan.
Is it possible to jump directly from 5.00 to 6.08? ... I think no... so I've just read PAM but it's so pessimist. So, I understood that:
Is it not possible to upgrade the system to EHP7 or 8 You have to perform following steps.
1. From the current level ECC5 to ECC6 with NW 7.0 SP level 30 & above. you have to check the PAM 32 bit support.
2. Do the system copy from ECC 6 wtih NW 7.0 from 32 bit to 64 OS Windows 2012 64bit along with Unicode conversion.
3. From ECC 6 wtih NW 7.0 with kernel 7.21 ext to ERP6 EHP7 or 8, before that refer the SAP Upgrade & system copy guide and Note version interoperability.
