MySQL 4 to MySQL 5

I am being forced to convert an application from MySQL 4 to 5.

I thought it would be pretty simple. The problem I've run into is size.

The full database dumped into a sql file is 324MB. The MAXIMUM I am allows to import into the MySQL 5 created database is about 49 MB.

First question, is there a way to increase that? I'm guessing it's a server parameter & that the host (1 & 1 will not allow increasing it.

So I considered breaking it into pieces. There are tw individual tables that are themselves over 49MB. One is 115 MB & ones is 80.

I think I can selectively export the needed data in chunks under 49 MB each, I already did the biggest one; 18 MB in a csv file.

The real question is if I do the 4 or 5 largest tables individually, is there an easy way to export all the others in one "chunk"? There are a total of 64 tables, of course I understand I can do them one by one. I mean the 57 or 58 that I can lump together.

I am using phpmysql to to the exports / imports.

Hi rkorts,

49MB is actually too small for it to stop, in fact i have restored dumps which are in GBs in mysql 5

what you can do is check in the my.ini file and change the value of the variable  max_allowed_packet to something like 500 MB like shown below. (This is possible if you have direct access to the mysql server)


when you are changing this value make sure you have stopped the mysql service and then restart it.

also try restoring it using the mysqldump command rather than phpmysql.

Thanks; I found that if I used gzip I could zip the 118 MB (largest table) to 20 MB.

So I'll just load it in a few pieces.
