Storage engine

[Vikram A]

Hi,

I have one doubt; Please can any one give your view?

I have MYSQL version 5.1.x. 

I have some existing Databases in which the tables are created using MYISSAM 
storage engine. 


Now i have another database which will use INNODB engine. 

My question is, If i set default engine as INNODB Whether it will make any 
misconduct on other MYISSAM databases?

Thank you!
