Make a backup of your database first, just in case, and then run the
schema upgrade script. To upgrade your MySQL database from the 0.9.9
schema to 0.9.10-incubating-RC1, you would use:

The need for that script is more explicitly listed in the manual, and
is included in a more obvious path within the .tar.gz of the database
extension, so you can expect this to be clearer when the release is
actually out.

Though there is a convenience script included within guacamole-docker
for producing the schema creation SQL script (""), there is
currently no similar script for conveniently producing the upgrade
script(s). They still need to be pulled either from git or from the
released .tar.gz for the extension.

Keep in mind that if your database is older than 0.9.9, you will need
to run the other relevant upgrade-pre-*.sql scripts first, as each
script applies only the changes made between two releases.
