Maybe this works:

disable auto sync in bootstrap app
Disable auto sync in all child apps
Scale all deployments and statefulsets to 0
Shut down cluster (maybe delete bootstrap app before)

a oneliner in case argocd project is deleted before the apps. this oneliner deletes all finalizers of all apps:

for app in $( kubectl get applications -n argocd --no-headers -o custom-columns=":metadata.name" ) ; do kubectl patch application $app -n argocd --type json --patc
h='[ { "op": "remove", "path": "/metadata/finalizers" } ]'  ; done
