Hello thanks before all, i've have a mysql 3.22.15 gamma , and 3.22.16 gamma in two Solaris on Sparc ( SunOS 5.7, 5.8 ). This mysql are in a site in "production", and i'd like to join the data bases in another data base in another machine ( solaris on Sparc ). I've installed in this third machine a mysql version 3.23.40 and i've readen about replication in mysql web. I've readen that if i want to replicate i must have minium version 3.23.33 in all machine's, and activate a log binary in all mysql's. I belive that i should "upgrade" the oldest database first, and then activate the binary-log in this , later , activate binary-log in the third data base ( 3.23.40 ), and then if i copy all databases that exists in the first two machine's ( mysqldump or copyng all data directoris ) , without stop it , and put it into the new mysql's machine , i can do it. I understand that log-binary only log update or delete's , and if i do it i'll be able to do it. The asks are , How i should upgrade of two new database's ?, install a new mysql version in another path ( for example if it was installed on "/usr/local/mysql", the new on "/usr/etc/mysql" ?, Can i install it on the same path and all the database existents will remain intact ? of course i'll do a backup before do something Can anybody help me ? thanks --------------------------------------------------------------------- Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?
