According to my point of view you have 2 òptions to retain your data. 1.You can create a small program that copies all the data from your old db to new db then use your new db with updated application. 2. Create a script file of the newly modified table (added/deleted columns) then execute this script with only for the first run of your program. Hope it helps.
