QSIG ON VCU

[COUNTOLIVER]

Hy,
I have to upgrade to BC11, a little network now in BC9.
All the QSIGs uses VCU.
I can't upgrade all sites simultaneously.

May I upgrade the network site by site?
Can the interoperability (upgraded and not upgraded exchanges) continues during the activities?

Just remember that VCU board is not supported in BC11.
You can swap the VCUs to Ericsson and get SPU2s, I believe.

You can upgrade site by site to BC11.
BC9 to BC11 interoperability is fine.
We did the same for a huge customer, going from BC9 to BC11.
