Theodore has asked for the wisdom of the Perl Monks concerning the following question:

As the MongoDB module will soon be EOL, what the Monastery wisdom says about using MongoDB from Perl?

I inherited an in-house (rather critical and very well written) Perl application which uses MongoDB as a back end. Replacing this application with another one is not an option for now.

Should I start looking for another DB to completely replace MongoDB (which is a rather daunting task)? If yes, any suggestions?

Should i try to keep the application working using the last version (2.2.0) of the driver?

Any other suggestions?
