MySql migration problem - urgent

Hello,

So far I used MySql 5.1 for Windows and if I wanted to migrate the whole database to another computer I did this:
- installed a MySql 5.1 on the new computer (yes I know I can install  from command line too)
- Stopped the server
- copied the old ibdata1 file and all the database folders from the old computer the the new one (data folder)
- Restarted the server and everything was fine

Today I installed 5.5 and I wanted to migrate the old 5.1 data and I wanted to repeat the whole process and to my greatest surprise there wasn't ibdata1 nor the log files in the data folder.

What can I do then? I have about 150 databases (it's a developer machine) so I don't want to export the Sql-s one by one.

Thank you

If the first time migrated MySQL on 5.1 was running, did you check the location of data folder from my.cnf?

I haven't got my.cnf, I have my.ini.

Before installing MySql 5.5 there wasn't MySql on that computer at all (the 5.1 was on another computer)

So do you "datadir" in that file?

It was set to:
datadir="C:/Documents and Settings/All Users/Application Data/MySQL/MySQL Server 5.5/Data/"
however at intall I set the installation directory (C:\MySql5).

I corrected the path, restarted the service.
Now I can see all the databases and tables but the stored procedures and views are not there.

How can I migrate them too, by copying? Where are they stored?

What is the output of the following query?

SELECT ROUTINE_TYPE, ROUTINE_NAME
    FROM INFORMATION_SCHEMA.ROUTINES
    WHERE ROUTINE_SCHEMA=<'dbname'>;

Chakravarthi AyyalaDatabase AdministratorCommented:
To add, replace the dbname with the dbname you are interested in.

the query result is empty for all databases.
Can I insert (do I have rights) into NFORMATION_SCHEMA.ROUTINES?

starhuAuthor Commented:
I exported all the routines from the old database and I wanted to insert into the new one but I got
"Access denied for user 'root'@'localhost' to database 'information_schema'"

Chakravarthi AyyalaDatabase AdministratorCommented:
information_schema doesn't really exist as a physical database. Rather it is a collection of views of data.
Hence, i doubt inserting data into information_Schema.

It didn't solve my problem because the stored procedures were not in the new database - I needed to downgrade to 5.0 so as to import all the data and stored procedures
