Can I easily print in PETG, using a PLA gcode?

I have a generic PLA gcode. Prints great in PLA. It's pretty complicated though, and I did a lot in notepad++ splicing objects together to create this gcode.

For a reason, I have to print this in PETG now. Can I simply use this PLA gcode, set some offset temperatures in OctoPrint, slightly live adjust Z... and print in PETG? Or do I have to recreate the gcode, because other changes are needed?

Normally, each filament type is assigned different parameters, such as temperature, speed, LA value, retract value, extrusion factor, and so on.
I also have PETG which gives ideal results at temperatures around 210 degrees C., but have never printed it with PLA settings. It is best to simply try it out on a small test part.

Statt zu klagen, dass wir nicht alles haben, was wir wollen, sollten wir lieber dankbar sein, dass wir nicht alles bekommen, was wir verdienen.

Perhaps you could slice for PLA and for PETG, determine the differences and apply them to your tweaked GCode file?
