CI version 1 to 4

I know this is a total long shot, but ....

A client has come to me with a site developed in CI version 1 (2009), and wants to know the cost of upgrading to version 4.

I'm tempted to quotr 100k just to get them off my back, but is there an upgrade path?


Best bet is to re-write it from scratch in CodeIgniter 4.

I would have thought this is an ideal opportunity to learn CI4 especially if:

1. the site is online
2. a database structure, tables, indexii etc are all set
3. screens are available
4. use PHP PDO instead of learning CI4 MySqli

Go for it Smile

Thank you both for the feedback, it was what I was expecting.
