Do temporary switch hardware need a license

Hi,

My SAP system is on a SAN

(OS AIX + application)

I need to test a switch to another hardware for few days so:

- the hostname is the same (Boot on SAN)

- SAP SID is of course the same

- only change is S/N of hardware

Is SAP started after the switch or I need a temporary license to start it ?

Is Solution Manager involved in it ?

Thnaks in advance
