I am assuming you want to copy assets (APIs, templates and domains) from one swaggerhub organisation to another? You can't do this in one click but you can export/import the yaml files per asset or use the registry api (https://app.swaggerhub.com/apis-docs/swagger-hub/registry-api/) to make this happen with a script.
However if it's just the link you want update you could also simply rename the organisation? It will change the links. But also, invalidate all your old links in other applications.
