Recently a customer request some way to migrate from older Sun server and solaris to newer server and Solaris but with one condition: need to preserve the hostid so the license server can use the license file with old hostid.
After some research, I find the followings possible solutions:
- Solaris 10 zone, one can use set hostid property to set hostid
- There is Dtrace heck to set hostid
- Using Ldom in CMT system, the hostid is tie to MAC address that one can assign to ldom
