I’d like your feedback on the following: at the company I currently working for, we have two major webMethods environmets: one implemented with webMethods 4.01 and 4.6 and one implemented with 6.1. The two environments currently communicate via a 6.1 Broker. The 4.x side uses TN, whereas the 6.1 side does not.
A project was recently kicked off to upgrade the 4.x environment to 6.1, so this way we’ll have a common environment across the board. However, the following question has recently come up: since we’re already embarking on an upgrade project, should we simply take some extra time (if any) and upgrade all of our environments to 6.5?
If possible, I’d like your opinion on the following:
(1) How much more effort (if any) would be involved in upgrading the 4.x side to 6.5 instead of 6.1?
(2) How easy/difficult is an upgrade from 6.1 to 6.5?
(3) If the 4.x side is upgraded to 6.5, but we are unable to upgrade the 6.1 side, will we run into issues when attempting to communicate through the 6.1 Broker?
(4) How much would we gain/lose by going to 6.5 instead of 6.1? (I understand I can somewhat get this information through the release notes and etc, but I wouldn’t mind learning about your real life experiences.)
