Can we use the same lib.so which we were using for ENGINE to replace it as provider
No. The OpenSSL <-> Engine interface is completely different to the OpenSSL <-> Provider interface. You need to ask the supplier of your ENGINE to update it to a provider (for which you will need a new .so file). Until then you are stuck using the deprecated ENGINE interfaces.
