We have been evaluating an option to migrate the VAN service from GXS to Sterling. We are trying to find out the tasks must be performed for this project. We have around 50 external trading partners, two mailboxes with GXS (TEST and PROD).
Also, we use Securemote VPN service to establish connection between webMethods and GXS servers.
I would appreciate if anyone can help me the tasks to be performed for this purpose, or can provide a documentation.
