hi Arun, direct upgrade from 6.5 to 9.0 is not supported. To see the supported paths for getting to the 9.0 release, please read the 9.0 webMethods upgrade guide. You will need to upgrade your 6.5 products to 7.1, 8.0, or 8.2 using the upgrade guide for 7.1, 8.0, or 8.2, respectively, and then use the upgrade guide for 9.0 to upgrade your products to 9.0.
