This is a good addition to the doc for this tool.
Now that we have two separate use cases, I suggest adding two new
sub-sections within the "Encrypt-Config Tool" section. Something like this:
**Key Migration**
In order to change the key used to encrypt the sensitive values, indicate
migration mode using the -m or --migrate flag...
.
.
.
old password â new key
old password â new password
**Existing Flow Migration**
This tool can also be used to change the value of nifi.sensitive.props.key
for an existing flow...
