# Porting list for OCP4 Fedora cluster > Tech Debt Matrix https://docs.google.com/spreadsheets/d/1nvDJdW7NgEPMJGnLMraQorPNap3R94kPhSqWvCkqTAg/edit#gid=0 We need to create a list of Fedora Infra services which we can begin migrating over to the new OCP4 cluster. From easiest, and least integrated to hardest and most integrated. Along the way we'll need to potentially update the Fedora Infra Ansible roles/playbooks to work with OCP4 API versions. eg some of the objects may have been techpreview in OpenShift 3.11 eg `v1beta1` or `v1alpha1`, but are now fully supported/finalised as `v1` ### Fedora apps currently running on OCP3.11 cluster(s) These need more information: ? application-monitoring - staging only ? coreos-cincinnati ? coreos-koji-tagger - production only ? coreos-ostree-importer - production only ? datagrepper - staging only ? datanommer - staging only distgit-bugzilla-sync - staging only, moved to toddler? fas-changes - production only, ???? ipsilon - moved to a vm, don't migrate sso ? not sure what this is it's only in staging test ? test-auth ? asaleh-test - prod only, delete? astepano - prod only, delete mrrolling-demo-project - prod only, delete * Things that can move anytime (still needs notice and outage) asknot bodhi bugzilla2fedmsg compose-tracker elections fas fasjson fedocal fedora-packages-static greenwave kerneltest - staging only mdapi message-tagging-service messaging-bridges monitor-dashboard monitor-gating noggin noggin-centos oraculum release-monitoring resultsdb resultsdb-ci-listener review-stats silverblue - production only testdays the-new-hotness waiverdb * Things that have NFS storage and/or cronjobs. docsbuilding docstranslation fedora-ostree-pruner - production only flatpak-indexer koschei languages toddlers - production only transtats zezere websites
