Moving to CDB architecture

Dear Maestros,
Most application vendors are reluctant to move towards oracle CDB environment although this is more than 4-5 years old features. All they mention oracle with non CDB. But ,our plan is to move towards CDB architecture since oracle 20c onwards this is compulsory.
Now, My concern is ,what actually needs to address while moving towards CDB or what prohibits from going to CDB.
It would be great to have some feedback from those who went through what I am facing now.
Cheers..

For the end user / application, so long as you are using service names in your connection strings (as opposed to SIDs) then it's exactly the same between a non CDB to a PDB. There were some newer things that weren't fully ported to the multitenant in the initial releases but they've all been cleared up now.
