With the basic rules it was rather straightforward what makes the jump of an egocast: Ego modifications do, morph modifications do not, as you're picking up a new morph at the other end. Also, since egos are probably among the largest chunks of data around, I assume that your data and software usually can come along as free luggage. Since Transhuman introduced upgrades, plug-ins and eidolons, 'i'm a bit fuzzy on that notion, though, and it comes down in part to computing platforms and emulation. Even today it is relatively easy (thank you, QEMU) to run software made for one processor architecture on another architecture, often even with little loss in performance. The transhumanity of Eclipse Phase probably won't have forgotten that that's a thing. On the other hand, diversified computing architectures (and a heterogenous computing environment) may help to stop or at least slow the spread of threats like the exsurgent virus; hence, there may be a trend towards de-standardization. Enter Transhuman. If you're running as an infomorph at your point of departure, what can you expect to find still working at your destination? My first, optimistic assumption would be "everything"; the benefit of standardization may outweigh that of diversification in many people's minds, especially since "Well, the exsurgent virus knows about emulation too; after all, it can even run on biomorphs!" Hence, infomorphs could take their whole "morph" with them. A somewhat more careful approach would be to distinguish between ego and mind-emulation software just like between ego and traditional morphs. Upgrades are changes to the ego itself, and the bits of them that do the actual computing will probably be compiled into a sufficiently general bytecode, so that they can be executed on any infomorph / eidolon. With current developments, I wouldn't even think it far out to assume that they're Neural Turing Machines. As far as infomorphs / eidolons (Why do we even have a term for something that is the infomorph equivalent of "it's not a splicer"?) themselves are concerned, however, they might be tied into station hard- and software, and thus must be bought or rented at thedestination. That would, however, lead the notion that infomorphs can migrate from device to device without it being a resleeving ad absurdum. After all, if one moved from a station's servers to a hand-held device brought in from somewhere else, wouldn't that then also require a new infomorph? Well... Opinions?
