I'll try to answer the below going by memory from what I've read of Ra and C's:
Andrew said:
Is it harder to make the transition from 4th STS to 4th STO or is it equal or less than the amount of work required for the transition from 3rd STS to 4th STO?
And if an entity does work from 4th STS to be 4th STO is there a greater amount of resistance in this realm against this change? In other words do the 4th density STS do everything they can, like they do here, to prevent a being from transitioning to a positive polarity?
Switching polarities is referred to as being easier (given increased knowledge and power) the further along either path one is, though the inclination is needed. (no one in an STO realm consciously chooses - with understanding that is, the Fall being an example of a choice without understanding of consequence - to switch to STS, relatively few in an - at any rate, in the 4D - STS realm choose to switch to STO)
4D STS society is referred to as being a ruthless power hierarchy where everyone is eventually settled into a rung (until the next power struggle occurs), so no doubt the dynamics could turn out turbulent - a being who went against the STS-grain would probably fall down the hierarchical ladder and face hardship. But here I'm just speculating.

Ra has also mentioned that the physical body will be required to "die" in order to make the transition to 4th (sorry can't find the exact passage)
The Wave, according to the C's, is the exception - in these rare times - reincarnation being the option otherwise available.

and then the C's have recently commented:
C's said:
A: What a glorious transition to 4th density STO. With maybe a quick stopover in 5th just to pick up a few things for the trip!
I'm curious as to why an entity would need to stopover in 5th? Given 5th, according to the C's is a "recycle zone" and where entities go to make preparations for their next incarnation. So could the "stop over" be to gather past life memories/experiences so that that being can make sense of its experienced existence in totality? Or perhaps to set preparations for it's next incarnation into a 4th density realm?
In an entity manages to be "ready"
and catch the Wave, then to my understanding no "stop-over" is necessary. However, an entity otherwise ready may well croak before the Wave arrives - and will then need to reincarnate. An entity could also - I think - so to say have gathered all the pieces during this life, but not been able to put it all together (perhaps going astray and missing something essential instead of focusing on it), and as such might need some contemplation before becoming fully prepared - let the experiences "ripen" to as to learn everything needed from them (this might be the case, I think, for quite a few people who have tried to go at their evolution without benefit of a network, who have come a long way but whose understanding has been muddied by some of the disinformation out there)
I'd guess "yes" to either of your questions.
Andrew said:
Also what is the process of incarnating into a 4th density realm? Does a being just materialize there or is there an actual birthing, and gradual maturation process for that entity in this new environment that it finds itself in?
In the case of transition by the Wave, materialization. Otherwise, don't know.
OSIT.
