World porting blues

[The classless]

Is there any way I could port 1.5.2 worlds or building to a 1.6.4 world

It all depends. If it is a modded world/building you might run into issues with the mods in question. Vanilla world/Building you can do wiht litle issue just you will need to travel outside the existing map for any new world gen fetures.

it depends on how many mods you have installed, and how many of those mods are updated, how much world you've generated and how good you are at figuring out mod conflicts. I've seen someone do an update from their world from 1.4 to 1.5 and it took him days to get everything straightened out and he had to write several programs to help him with the changes in configuration files

So in short I can't convert the whole world how about the buildings is there a way to copy and paste them on a fresh world

World Edit/SinglePlayerCommands and Shematica are really usefull for that task. Assuming ofc the block ids are the same across mc versions/mod versions and exist in the updated mods.

buildings are possible, but as lath said, it depends on the item IDs if they're the same in both versions or not...

so in the event that there are id conflicts could I change them all to match

Not just ID conflicts, the IDs for anything you care about must be the same or they will disappear/become glitched. This is actually what makes some transitions impossible, due to mods changing/adding/removing blocks, or changing how they handle a tile entity.

this. it's possible to do so, but it'll be one messy hell of a ID configuration
