How to make upgrade (copy data and schema ) from old DB version to new DB version ?

[ron bar yosef]

Hello all ,

my name is Ron

I'm new to MySql db , i want to know how can i do Upgrade from one DB version
to another DB version ?

i mean copy one db version ( schema + data ) to another db version ( a new version ) ,

copy the schema with all the data .

1) if i have old DB schema with data , i want to do upgrade to new schema
and copy all the data from the old DB version .

2) Do i need to write script to do it ? or the migration tool can help me to do this job ?

3) i want to check if it's valid upgrade operation , if you try to copy new db version to old db version , then the procedure should halt and warn you .

does anybody have idea how to do these process ?

thanks in advance

Ron
