Crystal reports migration

Question

Hi, I am currently working on a windows and web application which was developed in VS 2003. Now these two applications have been ported to VS 2005 and .Net 3.0. When the applications were ported the crystal reports dll(v9.1.9800.0) that were added as reference to the two applications have automatically changed to v 10.2.3600.0 which is for .net 2.0. I would like to know that whether i can use the crystal reports dll v9.1.9800.0 (VS 2003) in the newly ported application? Will the application work if i add the crystal reports dll v9.1.9800.0 as a reference to the newly ported application? Will the crystal reports dll v9.1.9800.0 be compatible with the newly ported application in vs 2005?. Thanks Ramya
