Issue with migrating database for Bugzilla 3.0

[tejas doshi]

Hi all,

I installed bugzilla 3.0 and was working fine till I tried migrating the mysql db data from previous version of bugzilla 2.20.2. These two versions are on different machines. I created .dmp file to get the data in bugzilla 2.20.2 onto bugzilla 3.0. Tables seemed to be updated(not sure if there is mismatch between the table structure), but after that upon trying to run checksetup.pl script, I am getting the following message
------------------------------------------------
"There was an error connecting to MySQL:

Access denied for user 'bugs'@'localhost' (using password: YES)

This might have several reasons:

* MySQL is not running.
* MySQL is running, but there is a problem either in the
server configuration or the database access rights. Read the Bugzilla
Guide in the doc directory. The section about database configuration
should help.
* Your password for the 'bugs' user, specified in $db_pass, is
incorrect, in './localconfig'.
* There is a subtle problem with Perl, DBI, or MySQL. Make
sure all settings in './localconfig' are correct. If all else fails, set
'$db_check' to 0."
---------------------------------------------

Upon pasting the bugzilla link onto browser it shows me the following error

---------------------------------------
"Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, root@localhost and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log."
----------------------------------------

Os Version information is as below.

Red Hat Enterprise Linux AS release 3 (Taroon Update 4)

Linux localhost.localdomain 2.4.21-27.ELsmp #1 SMP Wed Dec 1 21:59:02 EST 2004 i
686 i686 i386 GNU/Linux

MYSQL version installed is 4.1.22

Not sure what went wrong with the .dmp file. I am pretty new to bugzilla and mysql, any detailed help with this regard is greatly appreciated.

Thanks,
