Richard Janík updated WFLY-9877:
--------------------------------
Description:
This is only an issue for EAP, which has different versions than WFLY, for that reason,
all the versions mentioned here are EAP ones.
After some discussion with people who test migrations, we found that these protocols that
were deprecated in JGroups 3.6.x present in 7.1.0 and were removed in JGroups 4.0.10
present in 7.2.0 should be brought back in some form:
{noformat}
NAKACK --> NAKACK2
UNICAST2 --> UNICAST3
MERGE2 --> MERGE3
{noformat}
These are not in the default 7.0 or 7.1 configuration, so why do we need to translate
these like we do it for NAKACK2? Because these protocols can be expected to be present in
the 7.1 configuration due to migration from 6.x, where they are by default. Since, after
migration from 6.x, these will work with the 7.1 configuration, and since there is a
reason to expect them being used even if they are deprecated, we should not just silently
remove these protocols with the JGroups upgrade that is in 7.2 - the configuration file
from 7.1 should always work with 7.2.

After some discussion with people who test migrations, we found out that these protocols
need to be translated to:
{noformat}
NAKACK --> NAKACK3
NAKACK2 --> NAKACK3 (already done)
UNICAST2 --> UNICAST3
MERGE2 --> MERGE3
{noformat}
These are not in the default 7.0 or 7.1 configuration, so why do we need to translate

NAKACK, UNICAST2 and MERGE2 need to translate to their newer
variants
