OK I know nothing about this, I have to upgrade the SSIS Oracle by Attunity from 1.1 to 1.2

Found on hear that the 1.2 install will find and upgrade the 1.1 o 1.2, server already has Oracle 11G on it

Also going add a 1.2 Teradata I have the two 1.2 installs

Do I need to do anything to the SQLNET, LDA or TNSNAMS files?

Will this install break anything Oracle Cient, SQL linked servers etc...?

If it breaks something, I tested uninstall and it uninstalls 1.2 AND 1.1, assuming I would need install 1.1 back again and all should be OK if I need o back out

Thanks
