[TYPO3-dev] Changing a field to another type when not using kickstarter

[Brian Bendtsen]

Hi

I have been away from Typo3 1-2 month and I created an extension, which 
allowed the users to create some offers on the site. The offer has a 
time and date type field and I want to change that to a string type 
instead. Is it possible to just change it by using phpmyadmin?

I dont want to use the kickstarter since im afraid it migth overwrite 
som changes I have made to the code.
