How not to get lowballed due to less previous salary?

Same as text lol.

I'm a DevOps Engineer with 2 years of experience, have Kubestronaut badge and manage infrastructure across both AWS and GCP. Plus, I'm a junior engineer but still manage 4 other people in the team.

So, I'm definitely way underpaid at my current workplace, specially for the skills and knowledge I bring.

Now I'm about to have a discussion for a new offer in Bangalore, but since my current pay is on the lower end, I'm looking for around 100% hike (ideally more given my Kubestronaut status) but I have a feeling these guys will also lowball me. This will also require me to move from Mumbai to Bangalore.

How do I go about this?
