+### Support acknowledgement
+
+In November 2022, NetBird joined the [StartUpSecure program](https://www.forschung-it-sicherheit-kommunikationssysteme.de/foerderung/bekanntmachungen/startup-secure) sponsored by The Federal Ministry of Education and Research of The Federal Republic of Germany. Together with [CISPA Helmholtz Center for Information Security](https://cispa.de/en) NetBird brings the security best practices and simplicity to private networking.

 ### Testimonials
 We use open-source technologies like [WireGuard®](https://www.wireguard.com/), [Pion ICE (WebRTC)](https://github.com/pion/ice), and [Coturn](https://github.com/coturn/coturn). We very much appreciate the work these guys are doing and we'd greatly appreciate if you could support them in any way (e.g. giving a star or a contribution).

-## Migration from Store v2 to Store v2
-
-Previously Account.Id was an Auth0 user id.
-Conversion moves user id to Account.CreatedBy and generates a new Account.Id using xid.
-It also adds a User with id = old Account.Id with a role Admin.
-
-To start a conversion simply run the command below providing your current Wiretrustee Management datadir (where store.json file is located)
-and a new data directory location (where a converted store.js will be stored):
-```shell
-    ./migration --oldDir /var/wiretrustee/datadir --newDir /var/wiretrustee/newdatadir/  
-```
-
-Afterwards you can run the Management service providing ```/var/wiretrustee/newdatadir/ ``` as a datadir.
