OK thanks @codinghorror – so the instructions I followed are not current, since it installs Postgres 9.5: [Install Discourse on Windows for development](https://meta.discourse.org/t/beginners-guide-to-install-discourse-on-windows-10-for-development/75149) The production Docker version (w/Postgres 10) apparently creates a backup script that is incompatible with Postgres 9.5 even though the same version/build of Discourse is used during backup & restore. What do you recommend for my unique situation, @codinghorror? I need to import **a VERY large amount of content** (millions of posts from almost 100,000 members) from a proprietary forum system I wrote. [@bletch that should answer your question as well.] My idea was to have a local Discourse installation, use .NET’s Entity Framework Core to [scaffold the Discourse database](http://www.npgsql.org/efcore/index.html) and then directly add my data to the Postgres database using a .NET Core console app. Then backup & restore that database onto my production site (hosted on Google Cloud Compute in a Docker container). So, it would seem I need to use a full Docker/Ubuntu VM installation with Hyper-V on Windows 10 to achieve my goals? And not the (admittedly cool) new Linux Subsystem? --- _[View the full topic](https://meta.discourse.org/t/restoring-backup-fails-in-win10-ubuntu-development-environment/86893)._
