So I'm a little confused you said you had them in a secondary meaning you got the PET like 16 oz bottles or you have a PET better bottle carboy that you are using.
If you are talking about the 12 or 16 oz PET bottles, then you will lose carbonation. What you can do is have some more priming sugar into the bottling bucket and pour the bottles back in, where you would risk oxidizing the beer. unless you filled the bottling bucket with CO2 before hand. Then you could bottle them in the glass bottles. The only thing is I would use about half the sugar that you originally used.
If you are talking about the 5-6 gallon Better Bottle PET carboy, then no worries, when you go to bottle, just add priming sugar to the bottling bucket, and bottle them as usual.
