1a) I wasn't involved in the initial decision to switch, but gather it came down to expense and some unsupported perforce-related tooling.

1b) Absolutely! The switch from p4 could've been smoother, but git and access to the associated ecosystem is far ahead of Perforce for everything except storing binaries. We've been abusing p4 by storing electronics CAD files and similar, and do need to put some effort in to a new solution there. For source code, git (and the ecosystem of modern tooling it gives access to) is a huge improvement over p4.

A particular improvement has to do with network latency. Working from halfway around the world, I notice that p4 operations involving many files are very much slower than the similar git operations.

2a) I wasn't involved, but the particular project mentioned above had moved within the depot at some point, so guess the conversion tool that was used to move it couldn't manage that move. I intend to rebuild the older history in git, then see how viable it is to use git-replace to stick it on the beginning of what we have now.

2b) Yes. However, nontechnical concerns dominated conversation by far - to the detriment of the technical concerns.
