Upgrading hacked forum and adding new skin

[arob42]

I'll be upgrading vbulletin from 3.6.8 to 3.7.2 soon and have some hacks that I want to keep that have modified the database. I also want to ditch the existing skins and add a new one. So, can I do this:
Delete the old styles I don't want anymore.
Upgrade to 3.7.2.
Revert all mods to templates in the Default Style.
Install the new style.At this point I have a database with additional fields, tables, data for my hacks but no support in the templates. To add back template support, can I simply re-install the hacks choosing the upgrade option, and then manually apply any template edits that are needed?

I guess the alternative is to leave an old style in place that contains the hacks I want to preserve, upgrade to 3.7.2, check the differences in templates that need to be reverted, apply those differences to the new style.

Upgrading to 3.7.2 will only add extra fields/tables to your database, it won't touch anything that belongs to a modification.

Either one is do-able. Do which ever you feel more comfortable with. Personally I would have opted for the second approach, though it is more time consuming option and you need to know some level of HTML to see what is a modification and what may be just a upgrade change from 3.6.8. > 3.7.2.

I'd probably recommend the first option for yourself.
