Yes, they're going from 2020 to 2022 and then transitioning from 2022 to 2023. 
 
I'd like to think IT has reviewed the steps given, as they were successful in upgrading the test Vault. 
 
They voiced concerns at that time regarding how much time it took to complete the upgrade and are now recommending that we do away with Vault (due to all the time required to upgrade).
 
The steps followed by IT for the test server (which have not been successful for the production server)
 
    Create new MS Server 2019 server – make sure at least 500GB free space exists.
    Create new full back-up from "VAULT". (~4-6 hr)
    Copy backup to 2019 server. (~ 0.5 -1hr)
    Rename previous Vault to something else (.25hr)
    Rename new 2019 server to "VAULT"(.25hr)
    Run Vault 2020 Pre-check
    Install AutoDesk Vault2020 to (~1hr)
    Start ADMS – create new master vault if prompted
    Install all Vault2020 updates to "VAULT"(maybe 3) (.75-1hr)
    Restore backup from original vault server to "VAULT" (~4-6 hr)
    Start ADMS – possible the error of an existing “sa” account – stop ADMS and restart ADMS seems to fix this.
    Run Vault 2022 Pre-check (this may require booting IIS to delete VaultDM website)
    Install AD Vault2022 to "VAULT" (~1hr)
    Install all AD Vault2022 updates( maybe 2 updates)(~.25-.5hr)
    Start ADMS – Migrating the data should be prompted – accept the defaults (2-4hr)
    Run Vault 2023 Pre-check  (this may require booting IIS to delete VaultDM website, not VaultDT)
    Install AD Vault2023 to "VAULT" (~1hr)
    Install all AD Vault2023 updates (possibly only 1) (~.25hr)
 
 
Still not up this morning, day #4 w/o Vault.
