We are currently upgrading from Buyer 8.1 and Sourcing 4.3 to the 9R1 platform for both. This project includes a double-hop so to speak where we upgrade to Buyer 8.2 and Sourcing 4.4 prior to upgrading to 9R1. In two successful upgrades of our development and QA instances, we did not perform the suite integration between Sourcing and Buyer until both platforms were upgraded to 9R1. It has been recommended by Tech Support however to first perform the Suite Integration between Buyer 8.2 and Sourcing 9R1 before upgrading to Buyer 9R1. Unfortunately, this approach would require significantly longer cutover downtime due to the serial nature of the upgrade tasks. In other words, we could not upgrade to Buyer 9R1 until the suite integration was complete. We are also finding that the Suite Integration between Buyer 8.2 and Sourcing 9R1 is taking much longer than when both
platforms are on the 9R1. We believe this is due to hardware and network related differences.
For those who have upgraded from Buyer 8.2 and Sourcing 4.4 to 9R1 (or took on the dubious challenge of a double hop like we have), did you upgrade to Sourcing 9R1 and then perform the Suite Integration to Buyer 8.2 or did you upgrade both to the 9R1 platform and then perform the Suite Integration?
Any responses are greatly appreciated.
Thanks in advance
We did not do a double-hop. Earlier in the year we had upgraded to the necessary service packs to position us for upgrading to 9r1. We ran our Suite Integration at the very end of the process - after migrating Buyer, ACM, and Sourcing. Suite Integration is a long task - ours ran for 20 hours.
You should be fine running suite integration when both upstream/downstream are on 9r1. It is very common to run into data issues when running suite integration (especially on a double hop) and you would normally fix them in the Inspector. You can also plugin in the Weblogic port number (in the InternalURL param) in your AppInfo to improve suite integration performance.
You mentioned "You can also plugin in the Weblogic port number (in the InternalURL param) in your AppInfo to improve suite integration performance."
May we know how the "InternalURL" and Port numbers are used ? Must this value be the same as "IncomingHTTPServerURL" and Port no ?
Thought I would respond to my own question now that we have completed our upgrade.
We ended up waiting until both upstream and downstream applications were upgraded to 9R1 before performing the Suite Integration. This was the only way to complete the upgrade and associated data migrations we had to execute in the week of downtime we had to perform the tasks.
