Optimizely CMS 12 Upgrade takeaways

I've now gone through multiple CMS 12 upgrade projects. Each project had its own unique customizations and hence its own unique set of challenges when upgrading. I learnt something new, overcame a new hurdle, found/solved a new problem with every project. Some took quite a bit of time and synergy with Opti community, some back and forth on Opti support tickets, and solutions from other MVPs. So I thought it would be nice to put them all together in one place, for others on their upgrade journey, looking for same or similar solutions.

So here goes :

This first blog post talks about things like Marketing connector and Visitor group related issues.

This second one talks about small nitty gritty, more generic things, but if you don't know about them, they can end up giving you massive headaches.

Hope you find this one stop post helpful!

I am looking forward to hear other's upgrade stories and challenges faced/resolved, so please do share in comments if you encountered something unique.
