The old miest (version 1.15) works fine for "svymean" and "svylogit".

The new version of miest 2.0 is the one we recommend everyone to use. It
has been updated for Stata 7.0 and written for the most used procedures in
stata (about 25 different commands).
miest 1.15 was written with Stata 5.0 in mind and was written to work with
virtually every command used in stata at that time. It now is somewhat
unreliable in that it will bomb or give nonsense answers for some commands.
Which is of course why we updated the proc. Generally, however, for many
commands the 1.15 version works just fine. Whether it works for "svy"
commands probably depends on which svy command you use. My recommendation
would be to use the 1.15 version for the model you are estimating but check
by hand a few parameter estimates (the formulas that miest calculates for
combining parameter estimates are very simple and available in our article,
Schafer's book, etc.). If it works, then you should be fine. Again though
the version of the program that we are supporting and recommending for use
is the most recent one on Gary's web cite--2.0.

I have miest versions 1.15 and 2.0 (downloaded from Gary King's page
today). Version 1.15 runs with the svy commands. However, version 2.0 does
not. Does version 2.1 run with svy? If so, where can I get it? If not,
would results from version 1.15 be correct?
Thanks for your help.

I don't have Stata 8.0 yet but in Stata 7.0, miest saves the matrices in
memory. So if you want to access _mib or _miVCE, use stata's matrix
commands. For example, after estimation type.
matrix list _mib
matrix list _miVCE
Finally, just a reminder that you should be using the latest version (2.1)
of the miest and misum procedures.
