Partial change of home directory in Active Directory

Question

We are migrating data from one filer to another and we have home directories setup for a bunch of users under their Active Directory profile. Some users have \\\x.x.x.x\sharename\etc, some have \\\hostname\sharename\etc and some have \\\hostname.domain.global\sharename\etc.

I need to replace the first portion of x.x.x.x, hostname and hostname.domain.global with the new DFS name of domain.global\sharename\etc, leaving everything else the same.

How can I go about doing this?

Thank you.

One thing I should mention, every user is unique in that after the \sharename in the example, they have some other folder afterwards so i cannot just change them all to \\\domain.global\sharename\.. — nfoman, Sep 19 '17 at 19:07
I assume you mean that the new Dfs name is `domain.global` and not `domain.global\sharename\etc`? Please update your question with an example. — Bill_Stewart, Sep 19 '17 at 20:41
Hello, yes the new DFS name is domain.global, eg.. old: \\hostname\sharename\etc new \\domain.global\sharename\etc — nfoman, Sep 20 '17 at 20:20

You should be able to use regular expressions. Examples:

PS C:\> '\\1.2.3.4\sharename1\etc1' |
  Select-String '^\\\\[^\\]+\\(.+)' |
  ForEach-Object { "\\domain.global\{0}" -f $_.Matches[0].Groups[1].Value }
\\domain.global\sharename1\etc1

PS C:\> '\\hostname\sharename2\etc2' |
  Select-String '^\\\\[^\\]+\\(.+)' |
  ForEach-Object { "\\domain.global\{0}" -f $_.Matches[0].Groups[1].Value }
\\domain.global\sharename2\etc2

PS C:\> '\\hostname.domain.global\sharename3\etc3' |
  Select-String '^\\\\[^\\]+\\(.+)' |
  ForEach-Object { "\\domain.global\{0}" -f $_.Matches[0].Groups[1].Value }
\\domain.global\sharename3\etc3

The regular expression pattern is:

^\\\\[^\\]+\\(.+)

This translates to: Start with (^) two \ characters, get 1 or more characters that are not \, followed by a single \, and then one or more characters (.+). The ( ) capture the path portion and make it available in the string replacement (i.e., $_.Matches[0].Groups[1].Value).
