+## Running in Private Environments
+
+Redis is often deployed in private networks (VPCs, internal subnets) that aren't accessible from your local machine. The migration tool needs direct network access to Redis, so you'll need to run it from within the same network.
+
+### Common Approaches
+
+**Run from an existing host in the network:**
+
+If you have SSH access to a host that can reach Redis (e.g., your application server), you can run the migration there:
+
+```bash
+# SSH into a host with Redis access
+ssh your-server
+
+# Run migration using Docker
+docker run --rm -it \
+  -e REDIS_HOST=redis.internal \
+  -e REDIS_PASSWORD=... \
+  hookdeck/outpost:v0.12.0 migrate apply --all
+```
+
+**Kubernetes:**
+
+Run the migration as a one-off pod in the same namespace/cluster:
+
+```bash
+kubectl run outpost-migrate --rm -it --restart=Never \
+  --image=hookdeck/outpost:v0.12.0 \
+  --env="REDIS_HOST=redis.internal" \
+  --env="REDIS_PASSWORD=..." \
+  -- migrate apply --all
+```
+
+**Port forwarding:**
+
+If direct access isn't possible, you can forward the Redis port to your local machine:
+
+```bash
+# Example: SSH tunnel
+ssh -L 6379:redis.internal:6379 bastion-host
+
+# Then run migration locally
+docker run --rm -it \
+  -e REDIS_HOST=host.docker.internal \
+  -e REDIS_PORT=6379 \
+  hookdeck/outpost:v0.12.0 migrate apply --all
+```
+
+:::tip
+Use the same network configuration that Outpost itself uses to connect to Redis. If Outpost can reach Redis, running the migration tool in the same environment will work.
+:::
+
 ## Configuration
 
 The `outpost` CLI tool uses the same configuration as Outpost itself. Configuration can be provided through environment variables, a configuration file (using `--config` flag), or CLI flags (e.g., `--redis-host`, `--redis-password`).

 ### Migrations Included
 
 - **002_timestamps**: Converts timestamp fields to Unix format for timezone-agnostic sorting
-- **003_entity**: Creates RediSearch indexes for tenant listing
+- **003_entity**: Adds entity field to tenant and destination records for RediSearch filtering
 
 ### Running Migrations
 
-Migrations run automatically at startup. For production environments, manual migration is recommended.
+These migrations require a maintenance window and must be run manually before starting Outpost v0.12.

 These commands require environment variables for Redis connection (`REDIS_HOST`, `REDIS_PORT`, `REDIS_PASSWORD`, etc.). You can also use `--config` to pass a config file. See the [Schema Migration Guide](/guides/migration#configuration) for details.
