Unable to get developer's license to work, getting errors.

[kmevans]

Tried to apply new developer license after instance went to free license.

Got
Bad Request — Splunk.License: failed to add because: cannot add lic w/ subgroupId=DevTest:xxxx@xxx.com to stack w/ subgroupId=Production

Looked in answers for an idea
https://answers.splunk.com/answers/141906/splunk-licensing-issue-enterprise-does-not-support-license...

reset it back to enterprise then tried again but get the same error.
Where do I go from here.

Try removing the old license first

Get hash value for old license ./splunk list licenses
Remove old license ./splunk remove licenses [hash from your license]
restart splunk
Install new one as you tried to do before
