Can Acrobat do batch conversion of 100,000+ documents in multiple native formats into PDFs with OCR-English and OCR-Spanish?

I am trying to figure out the right kind of software for a specific conversion job. I am not very tech-literate so please keep any answers in plain language.

We anticipate having 100,000+ documents in multiple native formats (definitely Office formats but also emails and perhaps some others common to an office environment) that we need to convert to PDFs. Most documents will be in English but a small number would be in Spanish. They would need to be searchable multiple page PDF format, 300 dpi, and must be OCR-English or OCR-Spanish depending on the language of the original document.

Is it possible and fairly straightforward for a person competent with the program to do a batch conversion of a huge file of these documents (or divided into separate files by language and/or file type if necessary) using Acrobat? Judging by basic information available it seems like it should be possible, but I have received one opinion from someone knowledgeable that it would not be straightforward and that people with some expertise would need to create some scripts to complete this and that they might take 12 hours to create.

Thank you.
