Thanks. I am in the process of doing that.
It should end sometimes in next few hours.
One more question - I am backing my wallet.dat in a few places after every transaction in my bitcoin core wallet (I rarely use it)
In case my computer crashes and I install a new version of bitcoin core, I know I should copy my backup wallet back to the wallet directory.
I still don't understand one thing - in the newly installed bitcoin core - should I simply use my old pass phrase in order to send bitcoins?
Is this pass pharse basically the one that is protecting my wallet? (I have chosen a very strong one...)

Yes, as CIYAM said. You can think of it like the password is protecting the file. It actually is, but not the entire file. Some information are not protected, e.g. your addresses and the label you gave them (if any). This is so you dont have to enter the password every time you start. This is also means if you set a new password you need to update your backups or remember both the old and the new password.
Oh and nice you are using core and the password topic is up, make sure you make regular backups. The more you use the wallet the more addresses are used and new ones are created. The wallet keeps a stock of ~100 address and private keys hidden from you until you need them, so you should make backups roughly every 50 addresses used (or transactions created) to make sure you can recover fully.
