HiI am a dedicated FS9 user as there still are a couple of things that I cannot get in FSX. Less and less so, but still.However, there also is an increasing number of sceneries that are only developed for FSX. It's not so much the individual airport sceneires - almost everyone I want also exists for FS9 - but those scenery packages which have some "landscape" as a theme as well. Things like Maldives, Tahiti, Papua New Guinea, Dangerous Airports, etc.Therefore I am thinking about installing FSX in parallel to my existing FS9. The use would be: default in FS9 (=where I typically do high altitude commercial flying), FSX only for some of the more VFR-type flying with scenery packages that only exist for FSX.Questions:1) Can FS9 and FSX co-exist on the same PC?2) Could they even co-exist on the same drive (my PC has two drives...)?3) I am an AI fanatic with something like 1,100 traffic bgls. Can I just copy paste them from FS9 to FSX and then see my usual AI traffic also in FSX?4) Same question for AFCADs where I spent a lot of time optimizing them for my needs. Can I just copy paste my AFCAD files from FS9 to FSX and have the gate assignments that I am used to?Other than that I would of course buy separately all the planes and landscape/airport sceneries that I want to fly in FSX. It's just that "environmental setup" which has cost me a lot of time to tweak that I don't want to setup from scratch again.Thanks for any thoughts on these questions and other things that I'd need to watch our for.

I have been using FSX and FS9 in parallel for the last couple of months and have found no problems whatsoever. To answer your questions:1) Yes. My computer is proof.2) Yes. My computer is proof.3) Yes and No: The WoAI packages generally use FS9-type bgl files which will cause problems in FSX. You may see no aircraft if you have "aircraft shadows" turned on. However, if you do not plan to turn it on, that's no problem. I myself am using MyTrafficX because it gives a very wide range of types of aircraft and generates lots of traffic without any complicated setup procedure. But yeah, in principal you cna use the WoAI files to, but if you want to use aircraft shadows, it'd be better to convert the bgl files to FSX compliant versions.4) I think yes.By the way, I do the same as you plan to do: heavies in FS9, the rest in FSX. OrbX's sceneries for FSX together with the Flight1 BN2 Islander is the best cash I spent on FSX and it's an experience you probably will never be able to get in FS9 that's quite the same.

Essentially Ditto to ThrainiI have FS9 and FSX on same HDD. And FS8 on another drive.I have always used my Ultimate Traffic for FS9 and custom flights and Ultimate GA and custom traffic- just copy and paste as mentioned.Until FSX airport design utilities became available I did use AFCAD and adjust airports to match new alignments in FSX. Couldn't utilize newer features but this was mostly for smaller GA airports not involving Jetways and I think I initially couldn't move taxiway markings but adjusted taxiways, runways and aprons and parking. Use the new tools for FSX since they do exist now so you can move buildings and taxi signs.Loyd
