Its a fun server nothing more, nothing less. So all you guys just "Withness" this Fun Server at its best.
get that new core from other parties.
It's not as simple as that because codebases and technologies are different.
You can't just slap our database onto a new core.
Furthermore there are known/unknown bugs in other cores aswell which have been fixed by VG already. Getting those right on the new core is a quest itself.
There's basically 2 paths to go:
1) Stick with current VG, adapt new core slowly on PTRs.
2) Swap entirely, try to migrate the database, patch the new core live.
Option 2 is definitely risky considering lost stuff noone notices at first, performance problems, attack vectors etc.
To my knowledge, everything was settle till AQ40. In AQ40 visc, ouro and cthun bosses werent working properly on that new core. So again to my knowledge, it was decided to swap these bosses from our current VG core. And again to my knowledge, it was decided to swap naxx from our current core to new core.
And again to my knowledge, there is already one back up made of our database+chars. Which is stored in high tight security so the loss of data factor is also out of the book.
And again to my knowledge, nothing will ever happen and there is no new core ever gonna happen.
