 ## Migration Status
 
-**Phase**: 4 in progress (20/35 services migrated)
-**Current**: Migrating services from GlusterFS → NFS
-**Next**: Finish migrating remaining services, update host volumes, remove GlusterFS
-**Later**: Convert fractal to NixOS (deferred)
+**Phase 3 & 4**: COMPLETE! GlusterFS removed, all services on NFS
+**Next**: Convert fractal to NixOS (deferred)
 
 See `docs/MIGRATION_TODO.md` for detailed checklist.
 
-**IMPORTANT**: When working on migration tasks:
-1. Always update `docs/MIGRATION_TODO.md` after completing each service migration
-2. Update both the individual service checklist AND the summary counts at the bottom
-3. Pattern: `/data/compute/appdata/foo` → `/data/services/foo` (NOT `/data/services/appdata/foo`!)
-4. Migration workflow per service: stop → copy data → edit config → start → update MIGRATION_TODO.md
-
 ## Common Tasks
 
 **Deploy a host**: `deploy -s '.#hostname'`
 **Deploy all**: `deploy`
 **Check replication**: `ssh zippy journalctl -u replicate-services-to-c1.service -f`
 **NFS failover**: See `docs/NFS_FAILOVER.md`
-**Nomad jobs**: `services/*.hcl` - update paths: `/data/compute/appdata/foo` → `/data/services/foo` (NOT `/data/services/appdata/foo`!)
+**Nomad jobs**: `services/*.hcl` - service data stored at `/data/services/<service-name>`
