 {{{
+== CLEAN HARD UPGRADE ON WINDOWS ==
+General Hard upgrade instructions are documented in [http://www.postgis.org/documentation/manual-svn/postgis_installation.html#hard_upgrade PostGIS Hard Upgrade]
 
+You need to do a hard upgrade if you are using a pre-alpha release of a major release such as the case with PostGIS 2.0
+or you are upgrading from one major version to another e.g 0.*, 1.* --> 2.*
+
+1. Create a backup of your postgis database as usual.  You can do this with pg_dump as that instructions describe or PgAdmin III by right-clicking on the database -> Backup.  Make sure to use "Custom" backup for format if you are using PgAdmin III.
+2. Create a new postgis database installed with the postgis version you want to upgrade to.  Note if you are using PostgreSQL 9.1 and PostGIS 2.0 -- you can use the new in psql or pgAdmin III sql window after you have created a new database
+to spatially enable it. 
+
+{{{
+CREATE EXTENSION postgis;
+CREATE EXTENSION postgis_topology
 }}}
 
+
+3. If you don't have perl on your windows box, download [http://www.activestate.com/activeperl/downloads ActivePerl] and install.  You can use the 64-bit or 32-bit version even if you are using 32-bit PostgreSQL. [http://www.activestate.com/activeperl/downloads].
+When prompted to do so, choose to add Perl to your environment path and map perl to .pl scripts.
+
+Note that ActivePerl also has packages for MacOS, Linux, but is generally not necessary for those platforms since they come prepackaged with perl.
+
+4. Create an upgrade.bat file with contents something like this:
+{{{
+set PGPORT=5432
+set PGHOST=localhost
+set PGUSER=postgres
+set PGPASSWORD=yourpasswordhere
+set THEDB=mydb
+set PGINSTALL=C:\Program Files (x86)\PostgreSQL\9.1
+REM note the below example is if you are on 32-bit windows choose which install path makes most sense
+REM set PGINSTALL=C:\Program Files\PostgreSQL\9.1\
+set PATH=%PATH%;"%PGINSTALL%\bin\"
+perl utils/postgis_restore.pl "mydb.backup" | psql %THEDB% 2> errors.txt
+pause
+}}}
+
+5. Edit the script accordingly to your path settings.  Note that utils folder is packaged with the PostGIS tar balls
+if not present in your PostGIS install. Download the tar ball for the PostGIS you want to upgrade too.  [http://www.postgis.org/download/]
+6. Right mouse click on the .bat file (you may have to choose -- Run as Administrator)
+7.  If all is working -- you should see a screen something like:
+
+{{{
+ALTER TABLE
+ALTER TABLE
+SET
+}}}
