> ... which cannot be upgraded yet ...
@Dirk, Are you able to talk about PSI's plan and time table to upgrade
or decommission these <= 3.13 IOCs?
Speaking only for myself. I would be more willing to spend time on
these sorts of issues if I knew there was an end date.

Title:
EPICS 3.13 clients cannot connect to EPICS 7 or 3.16
Status in EPICS Base:
New
Bug description:
Since commit 95fd255d "rsrv: ignore CA client version older than v4.4"
from Jul 30 2016, EPICS 3.13 clients cannot connect any more, even
though their CA version is V4.8.
The reason is that camessage drops the incoming CA_PROTO_SEARCH
messages because the 3.13 client has not yet sent a CA_PROTO_VERSION
message and thus the code reads client->minor_version_number as 0.
This is a huge hindrance for upgrading 3.14 IOCs to EPICS 7 when there
are still 3.13 IOC (which cannot be upgraded yet) in the network which
need to connect.
