I need to downgrade data from MySQL 5.7 to MySQL 5.1. are there any ways to do in simple steps? (backup and restore )T There is a solution is step by step like downgrade from 5.7 to 5.6, and then to 5.5.
The Following link says step by step
Make sure you're not using features from 5.7, that are not avaliable in 5.1, for example utf8mb4
encoding (needed for emoji characters)
Then most safe option is to mysql_dump
all databases via mysqldump, except for mysql
(actually you need mysql.user
table, but it's safer to recreate, other settings tables may and most probably will not fit)
Try restoring on staging server first, to see if restored db works the way you expect it to
