Hi Sreekanth,
Thanks for your reply.
Yes, we know IS 9.12 can use UM 10.5. After using UM10.5,
we now have a situation where we can publish doc types between 9.12 IS Servers or publish doc types between 10.5 IS Servers.
But the doc type cannot be published between IS 9.12 and IS 10.5.The Messaging Trigger cannot trigger the Subscribe service.
And there are no errors,We were wondering about that as well.
We installed the fixes for the IS 9.12. Please let me know if you need any more information.
