+# Migration Guide: grpc_fresha 0.6 → 0.10
+
+## Requirements
+
+- **Elixir**: 1.15+ (was 1.5+)
+- **OTP**: 25+ (was 21+)
+- **protobuf**: ~> 0.14 (was ~> 0.10)
+
+## Breaking Changes
+
+### Module Renames
+
+```elixir
+# Error module
+GRPC.Error           → GRPC.RPCError
+
+# Client adapters
+GRPC.Adapter.Gun     → GRPC.Client.Adapters.Gun
+
+# Server adapters  
+GRPC.Adapter.Cowboy  → GRPC.Server.Adapters.Cowboy
+```
+
+### RPC Response Tuples
+
+```elixir
+# Success - unchanged
+{:ok, response}
+
+# Error - now 2-tuple instead of 3-tuple
+# Before (0.6):
+{:error, %GRPC.RPCError{}, _extra}
+
+# After (0.10):
+{:error, %GRPC.RPCError{}}
+```
+
+### Protobuf Struct Construction
+
+protobuf 0.14 deprecates `.new/1` - use struct syntax:
+
+```elixir
+# Before:
+Google.Rpc.Status.new(code: 3, message: "error")
+
+# After:
+%Google.Rpc.Status{code: 3, message: "error"}
+```
+
+### HTTP2 Server Trailers
+
+```elixir
+# Before:
+GRPC.Transport.HTTP2.server_trailers(status, message, custom_trailers)
+
+# After (3rd arg removed):
+GRPC.Transport.HTTP2.server_trailers(status, message)
+```
+
+### Base64 Binary Metadata
+
+Binary metadata (`*-bin` headers) now uses standard base64 with padding:
+
+```elixir
+# Before: "woA"
+# After:  "woA="
+```
+
+## New Features (Non-Breaking)
+
+- **HTTP Transcoding**: REST/JSON gateway for gRPC services
+- **CORS Support**: Cross-origin request handling
+- **Mint Adapter**: Alternative HTTP/2 client (`GRPC.Client.Adapters.Mint`)
+- **Flow Dependency**: For stream processing
+- **Telemetry**: Built-in instrumentation events
+
+## Quick Migration Checklist
+
+1. Update `mix.exs` deps:
+   ```elixir
+   {:grpc_fresha, "~> 0.10"}
+   {:protobuf, "~> 0.14"}
+   ```
+
+2. Find/replace module names:
+   - `GRPC.Error` → `GRPC.RPCError`
+   - `GRPC.Adapter.Gun` → `GRPC.Client.Adapters.Gun`
+   - `GRPC.Adapter.Cowboy` → `GRPC.Server.Adapters.Cowboy`
+
+3. Update error handling patterns from 3-tuple to 2-tuple
+
+4. Replace `.new()` calls with `%Struct{}` syntax
+
+5. Regenerate protobuf files:
+   ```bash
+   mix protobuf.generate --include-path=./priv/protos ./priv/protos/*.proto
+   ```
+
+6. Run tests to catch remaining issues
