UK Person potentially moving to India (Bangaluru) …. Advice…

I work for a very large multi-national in tech (think top 50 Dow Jones), like every company we have a location in India which is growing. Plus I’m a highly technical leader (im a VP). They’ve asked if I’d like to go work out in India. My wife is up for it, so are my kids (I’m mid 40s). 2 year min commitment. I’ve worked in other countries before. Previously at another company I had a similar offer but shut down the idea immediately but now I’m more looking for an “adventure”. I always get on well with India staff (probably a reason why they’re asking me) Any of you familiar with what I should push for on the negotiation side? I’m assuming I’d want a large villa in a gated community paid by company (office isn’t far from Dream Meadows and other communities), private school for kids paid, 1 or 2 paid flights a year home to visit family? Stipend? Temp increase in salary while there etc? Any advice on the negotiation side would be invaluable. As I only want to do this if I’m more on the high side so feedback on what to push for would be good.
