 At this point tunnels should be set up and running a local build should talk to the docker-compose services on the droplet.

+### DB migration
+
+**Option 1** - run docker-compose (WITHOUT the override) and copy the existing DB: 
+```bash
+# on the droplet
+docker-compose up --force-recreate netmaker
+docker cp netmaker:/data/netmaker.db .
+# on the host
+scp DROPLET:netmaker.db data 
+```
+
+**Option 2** (CE ONLY) - re-run nm-quick (WITH the override) to re-create the DB:
+```bash
+wget https://raw.githubusercontent.com/gravitl/netmaker/NET-246/read-def-config/scripts/nm-quick.sh
+chmod +x nm-quick.sh
+env NM_SKIP_BUILD=1 ./nm-quick.sh -b local -t BRANCH_NAME
+```
