Well, it is not totally different. There are some significant changes though.

The only things that are stored in the database are the settings that IH uses ( set in configuration>>images ). You will probably want to go through all of those anyway and have a look at some of the new options.

There shouldn't be any problems.

I understand that IH4 is totally different from IH2 which is why I am concerned that something may go strange with the install since I'll be using my existing database.

Thanks in advance for your help and guidance
