I am attempting to upgrade OTRS using the instruction from http://doc.otrs.org/3.0/en/html/upgrading.html . I am unclear as to what to do on  a few of the steps as well as getting errors.

It says to look for the files in opt/otrs, however the 3.0.10 version files are in /opt/otrs-3.0.10, so I have to traverse that directory to run any of the commands.

Step 6

Themes

Step 7

SetPermissions.pl, Not sure how to apply this

Step 8 MySQL:

  shell> cat scripts/DBUpdate-to-3.0.mysql.sql | mysql -p -f -u root otrs, I get a password prompt which I understand but it also says no file or directory found?

Step 9

        shell> scripts/DBUpdate-to-3.0.pl, No File or directory Found

Step 10 

MySQL:

        shell> cat scripts/DBUpdate-to-3.0-post.mysql.sql | mysql -p -f -u root otrs, same result as step 8

Step 11

        shell> bin/otrs.RebuildConfig.pl

        shell> bin/otrs.DeleteCache.pl , never seems to do anything

Not sure what I am doing incorrectly

Thank you,
