I've inherited an old TeX tree that contains multiple versions of TeX and I'm attempting to determine what local changes were made to specific versions. I understand that in certain cases our binaries were patched in addition to any local style files.
I'm currently looking at our TeX Live 2011 tree. This was installed using the internet installer back when that release was current.
My original plan was to install the archived historic release of TeX Live 2011 and then compare the two directory structures to highlight our local changes.
Since the archived TeX Live 2011 tree also contained files for the internet installer I attempted to run these with the slight chance these might install TeX Live 2011 similar to our original release. This does not work.
Is there a way to install TeX Live 2011 to replicate most of our original installation tree? Or should I be looking at the ISO images?
I realize this is not a common request. I'm attempting to pick up this TeX tree and determine what others have done in the past.
Thanks in advance for any advice.
