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?

Thanks

Hi @Chip Gore !
extrapolating Vic's very valid comment:
- if you have to take the sour apple of migration, let it be the last time.
- why not install WSL2 and migrate into a Linux environment. Or even into a docker scenario

You can easily do this by replacing two values in the registry.
Just checked on Caché & IRIS: SMP and Terminal (##class(%SYS.System).GetInstanceName()) displays the new instance name.
Upgrade/Deinstall work fine too.

If desired, you can also replace the service names (private Apache, etc.).

stop IRIS
close IRIS Launcher (aka Cube)
open regedit (run as Administrator)
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"
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"
start IRIS
Profit! Now the instance name is ABC.

Sorry Chip, I'm afraid you're out of luck. On Unix there's "iris rename" but this doesn't work on Windows because of registry stuff.

To rename an instance on Windows you'll have to migrate.

Vitaliy Serdtsev What are those two values in registry?
