Not realyl. You simply deactivate it on the old machine and install it froim scratch on the new one. Come back with specific issues if and when they arise. No need to lose sleep over something that people do every day and that works in most cases without a hitch.
In addition to Mylenium's comments, Adobe allows for two installations and Activations on one's personal computers. If you have NOT already installed and Activated on two machines, then you have one more installation and Activation available to you.
Now, if that desktop is going to be decomissioned, you WILL want to Deactivate that copy of PS, before you wipe the HDD, or tear the computer apart.
Sounds logical and easy. Thanks for the help!
Thanks for the reply. I will definitely deactivate on the old computer.
Photoshop functionality can be extended by add-on programs called Photoshop plugins (or plug-ins). Adobe creates some plugins, such as Adobe Camera Raw, but third-party companies develop most plugins, according to Adobe's specifications. Some are free and some are commercial software. Most plugins work with only Photoshop or Photoshop-compatible hosts, but a few can also be run as standalone applications.
