Are there any problems to be aware of when putting down SAVT over
existing sheet vinyl? Any additional prep needed, suggestions,
tips???

If the existing vinyl has a texture to it, it will telegraph through to
the new tiles. You can remedy that by using a floo rlevelling compound
which is essentially auto body putty that you trowel and smooth onto the
old tiles prior to putting on the new.
