I am currently in the process of having to transfer data from an old instance of a Dynamicweb database to a new instance. The problem I am facing is that the company we got the old database from made som changes to some of the columns.

They made the column AccessUserActive in the AccessUser table nullable, which means that there is a lot of rows containing a null value in that column. This means that I can't transfer the data to the new database because it does not allow that column to have null entries.

My question is then:
Will it be likely to cause any abnormal behaviour if I set all the null entries to the default values of the columns in question? The columns in question are AccessUserRead, AccessUserInheritAddress, AccessUserActive and AccessUserHideStat.

As a sidenote I am not able to do a backup of the database, which is why I am asking here instead of trying it out for myself :)
