Are there any changes in the API upgrade from 2.4 to 2.5 that would affect currently running systems?
We do not expect there to be any issues that would affect a current production setup.
The test2 system has been running the API 2.5 release for a number of months now without incident, so if you have done any testing there, you've been usigng the 2.5 release.
If you would like to test your application in production before the upgrade is done, you can point to the advance link: https://advancemessaging.easylink.com/soap/sync.
Wonderful. Thank you!
