Can the Apache bundled with TeamSite be upgraded to Apache version 2.4.35 or later? Thanks.
First please tell what version of TS you are running, also what OS
The version of TeamSite is V7.5 and the OS is using Solaris.
You can ask support, but very doubtful that there is a supported way to do that.
You should consider upgrading TeamSite to the latest version, it runs 2.4 (but i do not know the minor version)
I did once before get TS to work with a different Apache instance, but it was long and painful and completely unsupported. Basically I turned off iw.webd (internal Apache) ran another Apache instance and imported the Apache configs over from TS to the new instance. It was not pretty and things have changed a great deal since I did that 10 years ago.
