Problem:  

How to use PowerShell commands to transfer FISMO roles?

Solution: 

Active Directory PowerShell module.

Assumptions:  

FISMO PowerShell management requires Active Directory PowerShell module.

  Import-Module ActiveDirectory

Example 1.  Show forest FSMO roles (forest):

PS> Get-ADForest contoso.com| ft DomainNamingMaster, SchemaMaster

Example 2.  Show domain FSMO roles (domain): 

PS> Get-ADDomain contoso.com | ft InfrastructureMaster, PDCEmulator, RIDMaster

Example 3. Transfer single role to a domain controller.  

PS>; Move-ADDirectoryServerOperationMasterRole -Identity "DCX" PDCEmulator

#N.B., PowerShell FISMO role names:

0= PDCEmulator      
1= RIDMaster      
2= InfrastructureMaster
3= SchemaMaster
4= DomainNamingMaster

Example 4.  Transfer multiple roles.

Move-ADDirectoryServerOperationMasterRole -Identity “DCX” –OperationMasterRole DomainNamingMaster,PDCEmulator,RIDMaster,SchemaMaster,InfrastructureMaster



Example 5: Transfer all roles with numbers: 

Move-ADDirectoryServerOperationMasterRole “DCX” –OperationMasterRole 0,1,2,3,4

Example 6.  Transfer FSMO roles between domain controllers:

Move-ADDirectoryServerOperationMasterRole

That's It!
