It is possible to move the NetBackup catalog from one master to another master server running on the same "primary" platform (i.e. from a Windows server to another Windows server or from a UNIX or Linux server to another UNIX or Linux server) using a simple catalog backup and recovery operation as described in TECH77447 and TECH77448.
However there are many other operations that customers may need to perform at some point, including migrating the NetBackup catalog information from one primary platform to another (UNIX to Windows or vice versa), rename a Master Server or Media Server, cluster an existing Master Server, or merge multiple NetBackup domains, that should not be attempted without the assistance of either a VERITAS NetBackup consultant or a certified consultant from a VERITAS Consulting Partner.
A Master Server can be migrated to new hardware using one of the following documented procedures:
- Using catalog backup and recovery to transfer NetBackup catalogs between Windows master servers (TECH77447)
- Using catalog backup and recovery to transfer NetBackup catalogs between UNIX or Linux master servers (TECH77448)
These procedures, also linked below as Related Articles, require the new Master Server to have the same name as the old Master Server and cannot be used to rename a Master Server.
Media Servers cannot be renamed while they are "live" but they can be decommissioned, renamed and then added back into the NetBackup domain. More information about the nbdecommission command that can be used to decommission Media Servers is available in TECH62119.
For advanced migrations, not covered or prohibited in the documents above, to insure data integrity and seamless operation, operations must be performed by a certified VERITAS consultant or Consulting Partner, as they are not supported operations.
VERITAS 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 VERITAS consultants and Consulting Partners worldwide have been trained on these procedures and certified to deliver them in accordance with standards required by the VERITAS technical support organization.
VERITAS consultants and Consulting Partners will assist customers by determining the correct approach to take, planning the activity and executing the plan successfully with minimum disruption to the operational environment.
Please contact a NetBackup Sales Representative for assistance in engaging a certified VERITAS consultant or Consulting Partner.
Please note, a migration of this sort must be a part of a conscious, planned, and permanent transition, and should not be part of a disaster recovery process or any part of a disaster recovery plan.
