Hi all, Has anyone explored live migration of a Pulsar tenant/namespace from one Isolation group to another ? We have a use case where there are multiple tenants on a single isolation group and We want one of the tenants to have its own new isolation group.

I haven't digged into it, but my guess would be that the isolation group takes effect only at namespace bundle assignment time. Therefore only after the namespace bundle has been unloaded, the changes would take effect. please check
