Restore Backup after Upgrade from 4.7 to ECC 6.x

Hello Followers of SAP NetWeaver Adminstrator,

our company is considering to migrate from 4.7 [1] to ECC 6.0

At the moment there are two routes under consideration:

1) upgrade the existing system and keep data or

2) set up a new system and restore from system/client copy.

Gathering information for the alternatives I found an "Upgrade Dependency Analyzer". According to this SAP Application there shouldn't be any difficulties doing an upgrade [2].

I would like to pose two questions:

a) What are your experiences and why would you encourage one route over the other?

and more importantly:

b) How would Data archived under 4.7 still be accessible with ECC 6.0?

Looking forward to hear from the trenches!

Thanks in advance

Hannes
