No upgrade path. Since it is different OS you will have to rebuild it obviously. There is a migration tool to help you migrate user data and messages if you so wish. System configuration must be manually configured.

Make sure you meet the new hardware requirements as well.

read these for details:

Thanks whykap,
So may i believe that this is not belong to upgrade, it just supportted migration for some user level configuration .

Also,doed CCM 4.1(3) upgrade to 6.0 belong to this way? and only just some user level configuration can be migrated?

No, not the same. In CUCM after you install your 6.x image, you restore the whole database using the data migration assistant (DMA). You first run DMA on the 4.x version which converts the SQL db to Informix. Then you restore that to the 6.x version.
Fairly simple but time consuming.
