Hi All,

What are all the issues related in installing webmethods 6.1 and 6.5 to the same one Hardware?
Please suggest me how to configure both versions in all respects like IS,Broker & TN.Any suggestable response is highly appreciable and please elaborate it.

Thanks

Each WM product has slightly different steps for installing multiple copies of multiple versions on the same hardware. You will need to read the Administrator’s Guides for each product and have someone experience with installing WM products assist you.

Your question is too detailed to answer in a forum post. However, there are several posts here on how to install multiple copies of IS on the same server.
