Hi,
It is actually even more than the DB schema. The BIN protocol (used by
the clustering module) is different in 2.4 and 3.4, so the two nodes
will not "understand" one each other :(

Because of the database schema differences between the two versions,
you will not be able to use the same database to run both.
One migration strategy could be:
1. Convert the configuration and migrate the database structure to the
new version 3.4 on the current slave
2. Test the slave SIP logic using a separate IP address or port with a
SIP client that uses the slave server address as outbound SIP Proxy.
When everything works continue to the next step.
3. Switch over the cluster to the newly configured slave running the
new OpenSIPS version
4. Copy the configurations from the newly promoted slave to master to
the old master machine
5. Switch back to the old master

Hello,
I have an OpenSIPS 2.4 cluster I need to upgrade to 3.4. The cluster
is configured as an HA pair, with one active and one standby where
keepalived moves the IP between the two.
Can instances on 2.4 and 3.4 participate in the same cluster? I'm
hoping to update one "half" at a time while maintaining call
processing on the side that isn't being upgraded.
Regards,
Jeff
