Virus TI2 100% compatible to Virus KB?

[Barely]

Hi there
I know, technically they are compatible...
I got a KB right now and want to buy a TI2 in the near future,
the only thing that bothers me now is: Will it sound the same?
I have programmed some patches on the KB that are essential to some of my songs, and I fear they will sound different when imported to the TI.
I read a lot about how the TI sounds thinner than the KB. Is this true or is it maybe only judged by comparing preset sounds?
Is there an audible difference between the viruses?
Your help is much appreciated.
