Description
Our guarantee is that Nth major version can be upgraded to (N+1)th one, but we does not guarantee the same for (N+2)th version.
Say, to update 1.7 to 2.1 we need to update it first to 1.9, then to 1.10 and only then to 2.1.
We should clarify also what is a major version of tarantool: 1.7, 1.9, 1.10, 2. The way to enumarate versions was changed since 2.*.
