AC 5.3 to AC 10 migration

Hi GRC experts,

We are in the process of migrating of our data from GRC 5.3 to GRC 10.0

Our current set-up is we have created a different system for our 10.0 implementation which is running on NW 7 EHP2. All the plugins for the managed systems have already been updated to GRCPINW/GRCPIERP.

My question is, how we do we export the data from AC 5.3? I got a little bit confused on the pre-requisite from the migration guide, it says that we have to ensure that SAP Netweaver 702 SP06 is installed. Does that mean that we also have to do an EHP upgrade for our AC 5.3 system? Our AC 5.3 system is currently running on Netweaver 7.0.

Appreciate your quick response on the issue. Thanks.
