+# Configuration Migration to Smaller Providers
+
+1. Backup managed resource, composite and claim manifests:
+
+```bash
+kubectl get managed -o yaml > backup-mrs.yaml
+kubectl get composite -o yaml > backup-composites.yaml
+kubectl get claim -n $NAMESPACE -o yaml > backup-claims.yaml
+```
+
+2. Update deletion policy to `Orphan`:
+
+P.S: If this field is used in the composition files, we need to have special treatment
+
+```bash
+kubectl patch $(kubectl get managed -o name) -p '{"spec":{"deletionPolicy":"Orphan"}}' --type=merge
+```
+
+3. Generate smaller provider manifests
+
+```bash
+version_aws=v0.37.0
+version_azure=v0.34.0
+version_gcp=v0.34.0
+
+rm -f "sp-manual.yaml" && touch "sp-manual.yaml"
+rm -f "sp-family-manual.yaml" && touch "sp-family-manual.yaml"
+kubectl get managed --no-headers -o jsonpath='{range .items[*]}{.apiVersion}{"\n"}{end}' | grep -E '(aws|gcp|azure).upbound.io' | sort | uniq | while read -r line
+do
+  service=$(echo "${line}" | cut -d. -f1)
+  provider=$(echo "${line}" | cut -d. -f2)
+  if [[ ${provider} == "upbound" ]]; then
+    # azure.upbound.io is an exception where apiVersion does not contain the service name
+    # we have those resources in the family package
+    provider="azure"
+  fi
+  eval version=\$"version_${provider}"
+
+  for sp in config ${service}; do
+    filename="sp-manual.yaml"
+    providername="${provider}-${sp}"
+
+    if [[ "${sp}" == "config" ]] || [[ "${sp}" == "azure" ]]; then
+    # azure.upbound.io is an exception where apiVersion does not contain the service name
+    # we have those resources in the family package
+    providername="family-$provider"
+    filename="sp-family-manual.yaml"
+  fi
+    if ! cat "${filename}" | grep provider-${providername}:${version} > /dev/null; then
+    echo "apiVersion: pkg.crossplane.io/v1
+kind: Provider
+metadata:
+  name: upbound-release-candidates-provider-${providername}
+spec:
+  package: xpkg.upbound.io/upbound-release-candidates/provider-${providername}:${version}
+  revisionActivationPolicy: Manual" >> "${filename}"
+    echo "---" >> "${filename}"
+    fi
+  done
+done
+```
+
+4. Install config providers with `revisionActivationPolicy: Manual`:
+
+Verify that `sp-family-manual.yaml` files are generated with the correct content
+
+```bash
+cat sp-family-manual.yaml
+```
+
+Install the family provider(s)
+
+```bash
+kubectl apply -f sp-family-manual.yaml
+```
+
+Make sure the family provider(s) are in `Installed: False` and `Healthy: True` state:
+
+```bash
+kubectl get providers.pkg
+```
+
+5. Install smaller providers with `revisionActivationPolicy: Manual`:
+
+Verify that `sp-manual.yaml` files are generated with the correct content
+
+```bash
+cat sp-manual.yaml
+```
+
+Install the family provider
+
+```bash
+kubectl apply -f sp-manual.yaml
+```
+
+Make sure the smaller providers are in `Installed: False` and `Healthy: True` state:
+
+```bash
+kubectl get providers.pkg
+```
+
+6. Remove monolith provider(s) from dependsOn. Build/push and update the configuration
+
+7. Delete monolith provider(s):
+
+```bash
+kubectl delete provider.pkg $PROVIDER_NAME
+```
+
+8. Update smaller providers with `revisionActivationPolicy:Automatic`:
+
+```bash
+sed 's/revisionActivationPolicy: Manual/revisionActivationPolicy: Automatic/' sp-family-manual.yaml > sp-family-automatic.yaml
+
+kubectl apply -f sp-family-automatic.yaml
+```
+
+
+```bash
+sed 's/revisionActivationPolicy: Manual/revisionActivationPolicy: Automatic/' sp-manual.yaml > sp-automatic.yaml
+
+kubectl apply -f sp-automatic.yaml
+```
+
+9. Verify that MRs and providers are ready:
+
+```bash
+kubectl get managed
+kubectl get provider.pkg
+```
+
+10. Find new dependencies and add them to `dependsOn`:
+
+```bash
+providers=( "aws:v0.37.0" "gcp:v0.34.0" "azure:v0.34.0" )
+
+for pp in ${providers[@]}; do 
+  provider="${pp%%:*}"
+  version="${pp##*:}"
+  smaller=$(grep -irn ${provider}.upbound.io/v1beta1 ${CONF_PATH} | awk '{print $3}'| cut -d '.' -f 1 | sort | uniq)
+
+  for s in ${smaller[@]}; do
+    if [ $s != "azure" ]; then
+      echo "- provider: xpkg.upbound.io/upbound-release-candidates/provider-$provider-$s";echo  "  version:  \">=$version\"";
+    fi
+  done  
+done
+```
+
+12. Build/push/update the configuration to the new version
+
+13. Update deletion policy to `Delete`:
+
+```bash
+kubectl patch $(kubectl get managed -o name) -p '{"spec":{"deletionPolicy":"Delete"}}' --type=merge
