Welcome to the Q&A Forum

Hi I have a company for example: abc.com and they have a subdomain def.abc.com with a lot of errors. These errors i believe affect the parent domain abc.com. So my company would like to redirect the subdomain to another domain altogther ex: xyz.com Can i redirect the subdomain def.abc.com to another website domain? Would this affect the parent domain in a good or bad way? Or should i be using an external links to point to a new domain for the subdomain? Trying to think what's best for SEO and the parent domain. Thanks!
