All these days I'm aware of the fact that there is no way to migrate backups from one backup tool to other . For example EMC Networker to Veritas NetBackup or Veritas NetBackup to Veeam etc. However I have been asked to explore few options to migrate /merge our sites that are using different backup products without losing previous backups. The old systems have to be decommissioned anyways in the end. Few sites use disk appliances (of different vendors)as backup destinations, few use tapes.
What is the best approach to consolidate all these sites and migrate all backups to Veritas Netbackup?
Also in future, if I will be asked to migrate from Veritas NetBackup to some other backup vendor, do we have any options?
You will need assistance from specialised consultants.
Please see this post by @StoneRam-Simon_ :
Another option would be to restore longterm retention backups and re-backup with NBU.
Allow short-term retentions to expire naturally over a couple of months.
As always , thanks for your prompt response. It seems Tranzman backup migration tool is still not fully developed or support all of the backup products. We have sites with EMC Networker, HP data protector, Microsoft DPM, TSM , veeam.
Also who should we approach if we plan to migrate to or from these products. Let's say if we want to come out of Netabackup and migrate to one of the above products, does Tranzman tool support it ? (I see it is still in roadmap)
Also restoring them to some other place and re-backup using NetBackup may not be possible in our case as we have huge data and of different types like DBs, flat files etc.
