You will be OK keeping the secondaries at the same temp as you had for the primary. However, I think the beer is even better if you can keep the secondaries cooler. I put my secondaries in the refrigerator after I'm sure they are done fermenting and I get very clear beers. The only problem with this is that the yeast drop out. I keg my beers and force carbonate so I don't need to have yeast in suspension for conditioning.
