Hello

I have got confusion with these products and their relation.
We are using IBM HTTP Server 1.3.28, WAS 6.0 installed in 2 different Linux machines. We are using WAS HTTP plug in V5.0 till now, we need to use V6.0 now onwards. Our HTTP Server doesn't support Apache 2.0. But now, we need to support Apache 2.0. Few questions formatted my mind on this are.
1. Can I give support to Apache2.0 without updating IHS 1.3.28?
2. If I can't give support to Apache2.0 with IHS 1.3.28, Will Apache2.0 automatically installed if I install IHS 2.0x version?
3. Does any one know best option to upgrade IHS 1.3.28 to IHS 2.0? Do we have any tools to do this(for Linux)?

I will be really thankful to you if I get any answers

Thanks in advance.

IBM HTTP Server is based on Apache Web Server. That means when IHS is installed, apache is already installed. You don�t need to install apache seperately when installing IHS.

Here is the IBM Info center link to IHS 2.0 which has some more info.

Thanks a lot anant, for the reply.
That means I can switch directly to IHS 2.0. Can you please tell me what's the best to way to upgrade from IHS 1.3.28 to IHS 2.0.

Do we have any tools which can automatically do this (ofcourse with some inputs from my end)?

Thanks in advance for your reply, guys.

The way I would do it install a instance of IHS 2.0 on the same server (if possible) and test it out. If every thing looks good, then start routing all your request to the new instance.
For any reason if the new instance didnt work out, then atlleast you can still route the requests to the old instance so that you dont loose your service.

Hope that helps.
