Last updated on JUNE 20, 2017

Applies to:

Oracle Communications Diameter Signaling Router (DSR) - Version DSR 5.0 to DSR 7.2.0 [Release DSR 5.0 to DSR 7.0]
Tekelec

Goal

We are preparing for several upgrade cycles of Diameter Signalling Router (DSR) in a customer environment from DSR 5.0 to 7.0 and then to 7.1.

While NOAM is upgraded to the newer version, some DSR nodes in the network will remain at lower version of an extended period of time and customer needs to be made aware of any restrictions that may exist while network is in mixed versions.

In each upgrade procedure (referring to DSR Softwar Upgrade Guide 7.0) the following statement is made:
"Provisioning activities at the NOAM and SOAM servers will have certain limitations during the period where the NOAMs are upgraded and the sites are not yet upgraded"

Please provide references to specific restrictions that may occur after upgrading the NOAM but before upgrading SOAMs with the below combinations.

Scenario 1: Upgrading NOAM and FFA site from 5.0 to 7.0

All other DSR nodes in the network remain on 5.0 and might be for a long period of time (weeks, months).

  1. What are the provisioning restrictions (if any) that might exist between NOAM in 7.0 and DSRs that are on 5.0?
  2. Pls detail what operations are not permitted (or point to where I can find those).
  3. Pls list if there are any DB replication/merging restrictions between NOAM and SOAM while on the above mixed releases and weather such restrictions impact customer's operations in any way.

Scenario 2: Upgrading NOAM and FFA site from 7.0 to 7.1

All other DSR nodes in the network remain on 5.0 and might be for a long period of time (weeks, months).

  1. What are the provisioning restrictions (if any) that might exist between NOAM in 7.1 and DSRs that are on 5.0?
  2. What are the provisioning restrictions (if any) that might exist between NOAM in 7.1 and DSRs that are on 7.0 (when those are upgraded)?
  3. Pls detail what operations are not permitted in any of the above combinations.
  4. Pls list if there are any DB replication/merging restrictions between NOAM and SOAM while on the above mixed releases and weather such restrictions impact customer's operations
