To the OP: You are unlikely to find the salary much different from what you made in OR. Maybe 10%. Maybe 20% uplift in TCOMP if you're really lucky and still are employed (It's easier to find a job when you already have one). Remember, there are plenty of H1B's competing for those jobs at "CurryCom". I would not expect much of a relo package, if one is offered at all. Don't expect them to match lost RSU's or bonuses. Who do you think you are? Fat-Boy Murthy?
You will find that the cost of living, especially housing will be considerably more expensive versus OR. Just take a look on Zillow to see what's for sale around Hillsburrito versus anything proximate to "CurryCom"
Additionally, everything will be more expensive. You will contend with somewhat higher income taxes, plus the addition of Sales Tax on just about everything you buy (8% in San Diego?), so your disposable income will only be worth ~92% of what it is in OR.
Depending on your spouse, kids and housing situation, you may be better off finding something locally, even if it takes a while (especially if your spouse is currently employed). If you're single and currently rent, it won't be so painful, but you will still have to make some adjustment to your expectations.
Everyone's situation is different, but for most, a move to either the Bay Area, or San Diego will involve a lifestyle downgrade - why else do you think so many Californicators retire and move to OR?
