I need to perform a DB migration from Server A to Server B.
Server A: MySQL version installed 5.0.6
Server B: MySQL version installed 5.6.20
OS: Both are running RedHat Linux 64bit. 16 RAM memory.
There are MyISAM, InnoDB, Archive databases.
Total size about 4TB.
Largest MyISAM database = 3.2TB
Largest InnoDB database = 85GB
I took a mysqldump on the largest InnoDB table (85GB)
time /usr/local/mysql/bin/mysqldump -uroot -p --extended-insert --single-transaction ABCEx > ABCEx.sql
After running for 5 hours, the dumpfile has grown to 145GB and yet to finish.
-rw-rw-r-- 1 mysql mysql 145019313099 Mar 2 05:12 ABCEx.sql
I am concern on the export time and also import. Any help to expedite this?
MyISAM tables migration, I read that I migrate them by coping the .myd .frm .myi files from Server A to B. Can provide some guide or link if any one has done before? We are talking of 3.2TB of
Please help....much appreciated :)
