Vishal,
You just need to install the postgis scripts for 1.5 in the database (and copy over the postgis-1.5.dll etc in the lib folder). Both can coexist on same cluster as long as they are in different databases. If you look at the zip download packages we have the batch file will install the postgis in the specified database PostGIS 1.5: http://www.postgis.org/download/windows/#windbinaries PostGIS 2.0: http://www.postgis.org/download/windows/experimental.php#PostGIS_2_0_0 The only thing to keep in mind is currently they will share the same GEOS and Proj. The PostGIS 2.0 has a slightly newer GEOS (geos 3.3.1 branch and I think the PostGIS 1.5.3 we packaged GEOS 3.3.0). Note: 1.5.2 we packaged with GEOS 3.2 which won't work with PostGIS 2.0. If you plan to run both, you should use the GEOS in PostGIS 2.0.0 since the PostGIS 2.0.0 GEOS will is backward compatible with 1.5.2 and 1.5.3. Let us know if any of this is unclear.
