I have some basic doubts regarding the 9.5 upgrade process,
Is it possible to migrate the IS packages and process models from 8.0 to 9.5 directly or should i first migrate to 8.2 then followed by the migration from 8.2 to 9.5
For the IS packages, You can use Deployer to extract the packages from old to new envt. For BPM process, you can export the old process and import them in the latest Designer ad then publish it directly to the new version.
For more detailed info, refer to chapter 10 of webMethods 95 upgrade guide.
