One is to check whether there is a db change needed to make the old db into a newer format, you should do backup, and work on the restored copy on another machine.

Back to your question:
First you should check whether mysql on the 6.5 system is accepting connections from outside, iptables -L INPUT --line-numbers
Telnet from 7.5 version to ip of 6.5 version port 3306, do you see the mysql version in the greeting? Is the 6.5 version bound to port 3306 lsof -i:3306
Answers to the above will answer the question of connectivity.

Then on the 6.5 list the mysql.user table to see whether the user you are setting up for access from the 7.5 is allowed based on the host field and whether the user is password protected.

Check the documentation for 7.5 and see the transitions from 6.5. It could be that you would need to apply 6.8 and then 7.1 before getting the DB into the correct Schema to interoperate with 7.5.

A direct connection without a good backup could have an unexpected situation where the data is no longer accessible by eighter.

thank you very much for the reply. yes I had taken measures of iptables as both 6.5 sugar and 7.5 are on same esxi host as a vm's hence firewall( iptables) and selinux all are disabled and connectivity there found to be no issues.  root login validation found to be successful but data base does not get created also it is set with complete privileges,   the error while pointing the 7.5 to 6.5 mysql server was access denied I have allowed mysql root users login from remote on 6.5 think should also execute the below commands in 6.5 mysql server
6.5 server ip is 192.168.1.251 , please suggest should I have to execute the below on 6.5 where 192.168.1.235 is sugar 7.5
GRANT ALL PRIVILEGES ON database_name.* TO 'username'@'192.168.1.235' IDENTIFIED BY 'some_password';
FLUSH PRIVILEGES;

Please suggest is the above correct ones as this is production server

thanks in advance

Yes, you would need to run the grant query to allow username to login from 192.168.1.235 but the database must exist because it is part of the authentication, username from host using password connecting to database_name.

Try initially grant all on all.* to username@192.168.1.235
And change it after the database is created, or you can backup/restore the database from 7.5 to 6.5 system.
