You can use DNS to alias new machine names, so they appear to users as the
old ones, or, you can simply transfer the old names to the new instances.
Your "consultant" should have answered all of these questions, though. I
strongly recommend you and management revisit the issue with them, and if
you can't get the answers you need, get a new consutlatnt. Quickly.

With the exception of the PostGIS-related immediate issue, your question is
a little scary. It focuses on what I consider basic system administration
skills, and should be something your sys admin knows cold. If (s)he has an
opinion, respect it. If you've already lost them in the consultant process,
you could be in trouble.

“Big whorls have little whorls,
That feed on their velocity;
And little whorls have lesser whorls,
And so on to viscosity.”
Lewis Fry Richardson (1881-1953)
