Netbackup 7.7.3 to 8.1 upgrade

[Intore]

Hi, I have to perform the Netbackup upgrade for a customer that has the following configuration. This is my first time I upgrade an environment so I could ask trivial questions.

SERVER_1

• Main server as master and media server
• RHEL 7.2
• NB 7.7.3

SERVER_2 (REPLY)

• Reply with master and media server
• Windows server 2008 R2
• NB 7.7.3

SERVER_3

• Media server (NB version 7.7.2)
• OPS (NB already upgraded to 8.1)
• Windows server 2008 R2

The console resides on another server at version 7.7.3

As the OPS is already upgraded I can proceed with the master but I have a doubt on how to manage the reply and also regarding the fact that the master servers include the media servers (SERVER_1 and SERVER_2).

The correct order could be the following one?

1st. SERVER_1  

2nd. SERVER_2

3rd. SERVER_3

4th. Server with the console

Thank you

Intore

In general, the list goes like:

1. Upgrade OpsCenter first
2. Upgrade Master server and check functionality (rollback if issues persist)
3. Upgrade Media server and check funtionality (rollback if issues persist) - media server with lower version works with upgraded Master server. Recommended to have master/media at same version though.

See upgrade guide: https://www.veritas.com/content/support/en_US/doc/125240132-131571482-0/v125240153-131571482

Thank you X2 for helping. I know that order. OPS is already upgraded. I need to know if there is anything to keep in consideration about the master replication because in the "Netbackup 8.0 Upgrade Guide" this aspect is not addressed.

Thank you. Intore

@Intore 

This is the first time that you mentioned 'replication'. 
Maybe this is what you meant with SERVER_2 (REPLY)

Are you referring to AIR (Automatic Image Replication)? 

About upgrades and AIR between different NBU versions -  
Please see this extract from NBU Dedupe Guide:  https://www.veritas.com/support/en_US/doc/25074086-127355784-0/AIR-127355784

The ability to perform Auto Image Replication between different versions of NetBackup does not overrule the basic image compatibility rules. For example, a database backup that was taken in one NetBackup domain can be replicated to a NetBackup domain of an earlier version. However, the older server may not be able to successfully restore from the newer image.

@Intore   you might want to run through Veritas SORT for NetBackup.

And if you use MSDP then I suggest that you open a support case and ask Veritas about pre-patching your MSDP disk pools (i.e. media servers) to aid the upgrade / conversion process.  But be careful if your MSDP disk pools are over 50% utilised.

Hi Marianne and thank you for replying. Yes, SERVER_2 is the replication of the SERVER_1. My doubt concerned any additional procedures to be followed in case of replication because I'll have to upgrade every environment component to 8.1 version.

Thank you

Hi sdo. I already performed the SORT on the main server and there every check is green:

Disk space for NetBackup deduplication upgrade --> Your Media Server Deduplication Pool does not require conversion.

Anyway I saw that the PureDisk occupied space exceeds 90%.

I'll try to open a support case in order to check with them if the current configuration/status could be fine.

Thank you
