Renaming and installed Instance of IRIS

Is there any way (on a Window machine) to rename an installed instance?  I installed my instance as 20201 and now I've upgraded in place to 2020.4 and I would like to change the instance name to be 20204, but I'm not sure how/where/or-even-if-possible to rename the instance.


Am I out of luck, or is this possible?


Product version: IRIS 2020.1
$ZV: IRIS for Windows (x86-64) 2020.1 (Build 217_1U) Tue May 26 2020 20:41:06 EDT

  1. stop IRIS
  2. close IRIS Launcher (aka Cube)
  3. open regedit (run as Administrator)
  4. rename instance name (let's say "ABC")
    1. [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Intersystems\IRIS\Configurations\ABC]
    2. [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Intersystems\IRIS\Configurations\ABC\Manager\PreferredServer] @="ABC"
  5. run IRIS Launcher (aka Cube) and rename server names. If you want, you can also do this through the registry:
    1. [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Intersystems\CACHE\Servers\ABC]
    2. [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Intersystems\CACHE\Servers] "DefaultServer"="ABC"
  6. start IRIS
  7. Profit! Now the instance name is ABC.
