Converting Files that have cross fades and maintaining those cross fades

Hello, hopefully I am in the right place.  I recently finished a project recorded in Sonar, and mixed and mastered using Sonar. The final step involved taking the mastered tracks. importing them into Pyro, and lining them up to check waveforms and such, but one of the steps involved some crossfading of the tracks. I was then given a CD that had my 11 tracks in CDA format. I was told this could be used to upload files to Disk makers for instance to make my final CD. I have a couple questions... If I upload the CD a song at a time, will it maintain the cross fade information? If I rip to MP3 format to upload to my Reverb Nation page, again, will the cross fade integrity remain? and wav format as well for Band Camp. I would think I'd have to upload the whole project at one time to make it work. I ripped the CD into iTuines but have not had a chance to check it yet. I found a program to rip from CDA to wav, but it appears to just take the songs as marked without the cross fades, unless I rip them all as one, which is awkard... first time I have worked with cross fading, and I'm trying to wrap my head around it... If this post is in the worng place please move it, and accept my apologies.
Thank You
