I've upgrade ELK 6.x to 7.X  
But I got error I haven't got when I use 6.x.  
I used with below index name pattern when 6.x  
If I modify the index name , it suffer to change whole system.

Q1. Is it added index naming rule when 7.x ?

Q2. Is there ignore or avoid the "invalid\_index\_name\_exception" ?

Thanks.
