If you're not having that serious of problems and you can handle the expense for the remainder of this season - then converting next year at startup is probably a good idea.
No doubt in getting your baquacil levels as low as practical results in less mess and a quicker time to convert. I have a cartridge filter - there was a lot of effort in cleaning it - bacquacrap - several times a day as I went through conversion. I think this is a big part of making the conversion easier - lowering the bacquacil level, other than that I'm not sure anything else matters as far as ease of conversion. I converted to start this spring. I assumed that my bacquacil level would have gone down over the winter, I was dismayed to discover that it was at the max - 50 ppm. I partially drained to get my level lower.
To give you an idea on my conversion - 18' x 36' ag pool - 14,000 gallons - bacquacil level at conversion about 15 ppm - used about 40 gallons of bleach for conversion - about 5 or so days to convert ...
I'm currently putting in about 1 1/2 to 2 bottles of bleach a day - I hope to raise my cya to reduce that at some point. Anyway, you can do the math on cost versus bacquacil and bacquacil shock. Is cost for the remainder of the season an issue? It doesn't sound like it.
You're going to have to replace the sand or cartridge filter after conversion - don't know about de filters, I assume something similar. Regardless of when you convert, that is still an issue.
I hope that's enough info to help you decide.
As far as how to convert during startup - my opinion:
Get your bacquacil level as low as possible - get your water level back up after winter and the pump and filter going - vacuum and clean as much crap off of the bottom of the pool as you can - start putting bleach in and raise to and keep at shock level until you can maintain chlorine levels overnight for a couple of nights - keep the filter system constantly cleaned ...
I was slow with the vacuuming and cleaning step - the algae will start growing fast ...
