I agree with both of your responses that it should not be an issue and the
"compatibility" page says it should be good as far as server/client levels
go. But since the docs have the very specific warning about upgrading the
servers to 8.1.2 before clients or *"If you do not upgrade your servers
first, communication between servers and clients might be interrupted."*, I
felt I should ask for empirical evidence that it wont cause problems. The
warning was not specific on what kinds of communications problems to expect
or if/how they can be addresses if someone decides to download and upgrade
their client simply based on the "yes, 7.1 servers are compatible with 8.1
clients" document and didn't see the warning I read.
Perhaps it is due to TLS 1.2 now turned ON by default. Either way, more
details/specifics from IBM would be helpful.
