This is tricky, because there are a ton of questions with only the vmware tag -- 1,090 as of the time I originally wrote this.
Note the sidebar where it says "related tags", pay close attention to this Related Tags sidebar:
- vmware-esx × 146
- virtualization × 144
- vmware-esxi × 111
- linux × 74
- networking × 63
- windows × 59
As for the idea of "rename the tag if the text contains x", I downloaded a copy of the server fault database and ran some queries:
- questions with only the vmware tag, and no other vmware related tags: 725
- of the above, with the string "esx" or "esxi" in the body or title: 157
That leaves ~568 questions (!) needing manual retagging. That's .. a lot. Really a lot.
edit: I have done the following, just now
when a question was tagged vmware only, and its body or title contained "esxi", I converted that tag to vmware-esxi (70 questions)
when a question was tagged vmware only, and its body or title contained "esx", I converted that tag to vmware-esx (92 questions)
when a question was tagged vmware only, and its body or title contained "workstation", I converted that tag to vmware-workstation (66 questions)
when a question was tagged vmware only, and its body or title contained "vmware server", I converted that tag to vmware-server (71 questions)
(ditto for specific-enough body variants of all the vmware-* tags..)
when a question contained both vmware and any other vmware-* tag, I removed the vmware tag so the more specific tag can be primary. (~450 questions)
I was skeptical, but we did indeed make a big dent in it with these heuristics. The vmware tag went from almost 1,100 to around 300. If you guys could retag a third or so of those, to get it below vmware-server I think we might be in the clear.
