# Instructions for Upgrading Crafter CMS from 3.0.17 on Windows¶

For Crafter CMS installed from a bundle, before starting the upgrade process from 3.0.17, we need to download the updated scripts for the Crafter CMS environment we want to upgrade here:

Next, unzip the file we just downloaded ENV-3.0.17-batch-file-fixes.zip and copy the files under \$CRAFTER_INSTALL\bin. Please note that the crafter-setenv.bat in these file fixes contains the default port. If you made changes to the ports you also need to make the same changes in the updated crafter-setenv.bat file.
