Migration in progress (long one, lasting over a month)

PM: Let's schedule a meeting to discuss migration progress

PM: Let's schedule a meeting to agree on what should we test

PM: Let's schedule a meeting to get specs of the new infra

Seriously, PMs. One 1 hour long meeting costs at least 4 hours of productive time (1 hour for travel, 1 hour for the meeting, 1+ hour for preparing for the meeting, 1+ hour for post-meeting discussions). And more often than not all meetings end with "We will come back to you later in regards to <some question not answered during meeting>" and it always means "we'll continue this chat via emails"

Why can't you first ask "do we need a meeting or can we sort this out via email?" ??? Or are you intentionally wasting everyone's time?
