Best Practices Portal Migration
We are planning at the moment an database switch on our portal systems.
Our systems are running on EP 7.0 SPS 14 and as the database we are using at the moment Oracle.
We want now to switch to DB2. The operating system stays untouched on AIX.
Mainly we are the portal for ESS / MSS applications.
Also during the switch a company also using our system will be cut off from the landscape. So we having a lot of content in the system that is not longer used.
We investigated two possible approach for realising the change.
1. Use of the hetrogenous system copy.
2. Export all content from the target system and import it into the source system.
What are the advantages / disadvantages of the two possibilites and which solution should be prefered?
