I wrote the same project(Front end and back end) using Yii1. Now, I changed the front end using Yii2 but back end are still running with Yii1(But,they are different projects) on same database. The problem is that Yii1 can’t access files from Yii2 uploads folders when Yii2 uploads files.Because, back end (Admin site) want to look upload files and also want to update.Is it possible to access each other? How can I handle it? (Sorry for bad English)
