Strange Installation Order

[Guest JTEK99]

Hi, folks. I've checked the PMDG Wiki and it's slightly helpful in this particular matter, but I'm thinking that my situation might be unique. I currently have installed for FS9:PMDG 737NG 800/900 (Boxed, standalone)PMDG 744 PaxPMDG 744 FreighterAll are up-to-date.Oddly, now after a few years, I'm getting a hankering for flying the 600/700 series which I purchased before the three listed above but hadn't re-installed in a couple of years.Now, if I install the 600/700 variant, will I have to be worried that everything is going to crash out? Will there be anomalies with the 737 series? The PMDG wiki points out that I can simply backup the PMDGOptions.dll file found in the /modules folder, then replace it after intalling the "737 series". Will that work in this case as well?Thanks very much for any information!

I would of thought that the newer 737 panel graphics and config files that came with the 800/900nwill also get overwritten. Might be easier just doing a reinstall from the start...

Ack! I was hoping not to have to do that (livery backups, config alterations, etc.), but I can see the point.I wish there was a simple way. :(
