Install Aras 12 for testing

Can I install Aras (12.9) on the same server where I have Aras 11.11 installed? (using a different install folder, Instance name, different database). Will I run into any problems with the v12.9 install? Will my v11.11 be affected in any way?


My system specs are:

Windows Server 2016


MSSQL 2016

Plenty of disk space and memory
