From the same bug report, id=90994:

[24 Oct 20:17] Brad Jackson

Version 8.0.13 was released on 10/22 and the change list says:

"Support for MySQL 5.5 by MySQL Workbench 8.0 was removed. If you still 
need to use MySQL Workbench on a MySQL 5.5 server, you can use MySQL 
Workbench 6.3"


I guess we're all stuck on the old version until we upgrade our servers.

Connections from mysql8.0 to mysql5.1 - bad handshake

[Jim]

I'm trying to configure replication of a mysql5.1 database master server 
to a mysql8.0 database server.

But the replication connection will not succeed.

I don't believe the issue is directly related to replication, because 
any connection attempt from mysql8.0 to mysql5.1 fails as follows.

As run from the mysql8.0 server:
$ mysql -h db5.1server.mydomain.com -u my_user -p
Enter password:
ERROR 1043 (08S01): Bad handshake

Given the following bug report, what I am trying to do does not sound 
hopeful:

https://bugs.mysql.com/bug.php?id=90994

I'm in the middle of a transition from centos6 to centos7. mysql5.1 is 
the standard mysql distribution in centos6. With centos7, I decided to 
skip mariadb and use the mysql8.0 distribution. My upgrade path would be 
much safer if I could get replication working as stated above.


Any thoughts or do I need to accept that what I'm attempting just isn't 
going to work?


Thanks,
Jim
