WLSM and WiSM are two completely different architectures, and seamless mobility between them, if at all possible would probably not be worth the effort.
Are you going to be converting a lot of APs? I would suggest converting only recent models like the 1131 or 1242 series and later, trade-in the rest and buy new lightweight APs for them. If you have 1020 series APs get rid of them now as they wont work with current versions of the Unified Wireless software. I would suggest a clean setup and cutover with the new WiSM as much as possible rather than attempting simultaneously have both up and running or slowly migration. You can install the WiSM module, connect, prime and test your new APs (you can disable the radios from the controller interface if needed to prevent interference with the legacy system). Once all the APs are ready and primed, set up your WLANs, enable only a test AP's radio and test the WLANs. Once everything is tested, you can quickly enable the new APs and WLANs and remove the old. WCS by my experience is overrated and not so easy to use, given the same budget I would take Airwave any day. Converting APs over from autonomous to lightweight is a pain, and also causes downtime, so budget permitting I would suggest that you trade-in and replace them as much as possible, especially if they are not n-capable. If a lot of the new APs you are buying are n-capable, you might also want to review the AP placement or do a fresh survey, as well as make sure the APs are connected to gig ports and existing POE/power injector can meet the power requirements.
