How to understand whether you are ready for a new level or not and you should not even stick your head out?

A little over thirty married and have children.

At the moment I work as an l1 support engineer for server products, storage within the framework of delivery and maintenance.
Although there was a choice between l1 support engineer at a world-famous company vs DevOps at a local company.

I chose the first one because I have never worked in an international company and this became very interesting for me.
In a large vendor from China (they do not need advertising, I can say that they are solving the 5G issue). Which has an office in our republic (one of the countries of Central Asia - I do not want to mention in the framework of privacy).

Prior to that, he worked in local support teams of various second-tier banks (although there were a couple of Russian banks) as a Linux/Unix/San administrator.

I think to try myself in the field of PM or IT infrastructure architect - storage&backup.
But in your own country, due to the narrowness of the market, it is extremely difficult to find one, since everyone knows each other and the places are already taken.
I think it can go somewhere.
Is it worth it?

Answer 1

1) you will never be completely ready. There is always the temptation to push a little more. it's about leaving the comfort zone, procrastination and other fashionable psychoheresy.
2) to enlist the support of the family (very important), the accumulation of a pillow for several months - and forward.

Answer 2

Well, if you can lift your ass off the couch, then you're ready, if you can't, then you're not ready.

Answer 3

Better to try and regret than not to try and regret.
It is also worth trying yourself outside the Turan region, in Turkey. Istanbul is a great city. Regional, cultural, national, linguistic affinity has not been canceled. Yes, the salary is higher.
Ps
I do not advise Moscow - I think you yourself have seen from the comments what is happening in the Moksha swamps. It seems that 90% of racists and cotton wool that will chirp at you about "partners", the West, the USA who want to blow up the region. (Although in fact it is Russia, a cancerous tumor in our region)
