Needed few clarifications on migrating my existing Tridion 2011 to Tridion 2013 SP1.
Firstly we do not want to disturb our existing environment unless we are sure that Tridion SP1 is working fine. So we are thinking of an approach where we purchase a new license and upgrade the Tridion 2011 databases to 2013 SP1 using the powershell scripts and install the Tridion package specifying the upgraded databases freshly instead of performing the long upgradation steps given in the Tridion documentation. After the install we will install all my extensions and tools once again. If everything works fine then in the end I'll once again update the current Tridion 2011 databases and switch those to the new Tridion 2013 SP1 in the content manager configuration settings.
This approach is mainly to avoid the downtime of our production environment and to make sure our installation doesn't screw our existing environment.
Please share your thoughts in this approach.
Thanks in advance.
