I work in a company with 5 full time devs only working on a big project with yii1.1.20.
For quite some time we have the upgrade to yii2 on the radar, it’s crucial for our clients to keep security up to date, so the project must be migrated before end of security patches. Also we are about to start developing a big new module, which I had in mind to do in the hybrid yii1-yii2 environment. Now that yii3 is on the way, I wonder what path we should take? Does it make sense to wait and integrate yii3 into yii1? Or should we start migrating to yii2 and when the time comes migrate again?
