opam 2.0 upgrades the format automatically when pinning a repository
with an older opam format.

You can run "opam admin upgrade-format" to upgrade the repository, but I'm not
sure of how to convert individual `opam` files. This seems like it would be useful in
order to upgrade working repositories for pinning purposes...

Seems the issue is mis-interpretation of a deprecated constraint. I'm using
Jane Street's opam repository [1], which contains constraints like:
available: [ ocaml-version >= "4.03.0" ]
After replacing this with a normal constraint in the `depends` field, it worked
fine. Is there a tool to convert old opam files?

I'm getting this:
$ opam install ppx_sexp_conv.114.10+84
[ERROR] ppx_sexp_conv.114.10+84 has unmet availability conditions: ocaml-version >=
"4.03.0"
So opam thinks my ocaml version is < 4.03.0, but I'm in a 4.03.0 switch. I've certainly
run "eval `opam config env`". I created a new switch with 4.03.0 to try it from
scratch, but get the same issue.
Sanity checks:
$ ocaml -version
The OCaml toplevel, version 4.03.0
$ opam info ocaml | grep all-installed-versions
all-installed-versions 4.03.0 [4.03.0] 4.04.0 [4.04.0]
Incidentally, I'm confused about the output of `opam info ocaml`. I have 6
switches on this computer. How come only 2 are listed above?
$ opam --version
2.0~alpha5
