Hi there, I'm looking to do an SMS migration from Attentive to Klaviyo to consolidate email and SMS in one place. I've never done an SMS migration before, but I have done 5? email migrations over my career, and some massive ESPs, so I'm thinking this won't be too bad. I have 2 questions I'm hoping people can help weigh in on; 1. Do I need Klaviyo's $3k onboarding services for this? The flows are very simple, and need to be burned down frankly anyway. Realistically we have less than 10 flows, and our signup units/optin modals need an overhaul. Based on the fact I'm essentially starting over, I don't think I need these onboarding services --- am I wrong? What are the 'gotchas' I need to watch out for when migrating? I've done my research, but again, this is my first time doing an SMS-only migration so there may be things I haven't thought of because I've never had to.…
