That depends on your services. I have done that procedure several times without shuting down services. You can also copy over your stuff once while services are running, then stop the services (and remount red-only if you think it's necessary) and perform a final sync that will transfer only the files that have changed [*]. That will be pretty quick, and the downtime will be short. > Both methods need a reboot in order to change the root fs... That's true. At some point you'll have to switch your root FS to gm0 ... That's not avoidable. > It is always better to design the system before it is installed... :-) Very true. :-) Best regards Oliver [*] E.g. you can use cpdup for that purposes, from ports/sysutils/cpdup. It's fast and easy to use. -- Oliver Fromme, secnetix GmbH & Co. KG, Marktplatz 29, 85567 Grafing b. M.
