I should have worded that differently. I meant migrating an existing production.

If you have an existing production which works well after years of improvement and stabilization, with people with a lot of expertise on it, you won't get that in 2 months, not the stability and quality nor the ability to troubleshoot it.

Startups start from scratch, don't have big workloads, also there isn't so much pressure to have a high quality service from day one because you don't have that much people consuming your services.

Thanks. Where "everything" is in the context of a transition or migration, rather than any kind of deployment, including an initial one, 2 months seems like a very reasonable minimum.

It's certainly in line with technical new hire productivity "ramp up" time estimates (typically 3 months?), which I would guess are a similar (if individual) case of change-of-mindset.
