Update / Migrate SAP XI 3.0 to PI 7.4

Hi Everyone,

Can XI 3.0 be upgraded to PI 7.4 or should a new installation of 7.4 be installed and then migrate the XI 3.0 SWC developments across.

• What happend to stack of abap?
• Can only migrate from SAP XI 3.0 to SAP PI 7.X (Abap+Java)?

Thanks in advance
