upgrading exe server for W2003

Hello, I use a 2.01 DB To install on a W2003 server, there is some problem A this time, for some reason, I don’t would to do a complete upgrade to 3.70. So, is it possible to use 3.70 executables (client + server) to run a 2.01 DB ? I hear that there is no problem But I hear too, that it’s not possible because data models are not the same ??? So, what should I do ? And after, If a would copy DB files to another server always in 2.01 for some new development, is it always possible, or my test server must be in 3.70 ?? Thx

There is no problem with 2.01 DB and 3.7 executables. Similarly you can upgrade the executables for test system
