+      You are attempting to upgrade the installation of geoshape. Before proceeding, you should backup
+      this machine. If it is a virtual machine, you should create a snapshot so that you can undo the changes
+      if there are any incompatibilities. In some cases, the database may no longer operate as expented resulting
+      in potential loss of data. Note that only some upgrades can complete successfully! Before continuing
+      you should review changes introduced between the geoshape version you are currently on and the version
+      you are attempting to upgrade to. There could be many backwards incompatible changes introduced at
+      any of the geoshape dependencies. In some cases, a clean installation of geoshape might be necessary
+      to get the latest functionality successfully. For example, the geoserver_data directory required by
+      the latest version of geoshape, may contain some configuration or scripts that doesn't make it
+      possible to simply keep your current /var/lib/geoserver_data directory. Similar issues could arise for
+      many other dependencies of geoshape. This script is only intended for advanced users! The safest way
+      the to upgrade geoshape is to create a new instance and migrate your data."
