Upgrade Vault and Consul helm releases

Hi All,
I need help and advise
I have an outdated helm v3 release of consul-0.16.2 and vault-0.3.3 deployed a my cluster
I need to upgrade the release to latest
what is the best approach to upgrade where there is a massive gap between versions
The stack is used in prodction workload
I can avoid a downtime durning upgrade but need them up again or revert back to previous version if the upgrade fails completely
Thanks in advance

I’m not sure anyone could tell you the pitfalls of such a massive version difference. My suggestion would be to do a completely new namespace and deploy a brand new instances of vault and consul and doing a backup and restore of your data. At least you’ll be able to test the environment before cut-over and at cut-over just switch your ingress.
