Can you give an example of an ID that you would like to change it to? If you're only looking to show a unique integer for each package, then updating the `packages`.`id_value` would suffice. Simply update the `id_value` for 6 to 7, and one of the two 5's to 6, resulting in, for example:
5 | Domain Registration (.com)
6 | Skilled
7 | Domain Registration (.net)
And of course, always backup the database, or at least this table, before making manual changes to it.
