Yes, you can (and should!) restart them one at a time to avoid downtime.

Hi Greg,
Can I restart daemons one by one online? Or there will be a down time before I restart all daemons?
Thanks
Choury

主题: Re: How to migrate ms_type to async ?
You just have the set the config option ("ms_type = async", I think?) and restart daemons. Both messengers use the same protocol and there's no migration in terms of data or setting up compatibility.
