    It should be easy enough to test:

    Perform catalog backup to disk on current master server.
    Install NBU as clustered master on Linux cluster to same path(s) as original master using same NBU version and patch level. Use same hostname as virtual master name. Ip address can be different.

    Do at least one failover and failback to ensure emm entries are correctly updated.
    Restore catalog on active node followed by nbemmcmd -updatehost command to update OS. 

    See:

    Using catalog backup and recovery to transfer NetBackup catalogs between UNIX or Linux master servers as part of a hardware refresh
    http://www.symantec.com/docs/TECH77448

    Disclaimer:
    A very good knowledge of NBU is needed to perform migrations like this.
    Trained consultants have a dedicated team of Catalog Manipulation specialists as backup when charging you for assistance.

    There are several points in this TN which could lead to support issues if things don't work out (but you will still have the old master!) :

    so does  its cluster Master to non cluster Master server with Different OS?

    http://www.symantec.com/business/support/index?page=content&id=TECH31385

    Symantec has developed comprehensive methodologies to handle a variety of reconfiguration requirements including the following scenarios:

    • Migration from an existing master server to a NetBackup appliance master server
    • Merging of two or more domains
    • Splitting of a domain into two or more domains
    • Clustering of a non-clustered Master Server
    • Renaming of a Master Server or Media Server
    • Moving a Master Server to a new machine involving a host name change
    • Moving a Master Server to a different platform/operating system (Windows to Linux/Unix or Linux/Unix to Windows)
    • Un-clustering a clustered Master Server

    A number of Symantec consultants and Consulting Partners worldwide have been trained on these procedures and certified to deliver them in accordance with standards required by the Symantec technical support organization.

    If you are Un-clustering, then please contact Symantec consultants and Consulting Partners as Nagalla recomended. There is no documented way to do this as its a fairly complicated process.

    If this was just a linux to linux move you would normally just follow TECH77448, but because you are clustered, there will be more steps and further complication to the migration.
