Yes Rossi did promote Ni->Cu at one time, but it is not his current spiel. AFAIK – since the death of Focardi, Rossi no longer strongly promotes any theory for gain - but it may still be on his blog. Kullander also admitted the copper found was of natural isotope distribution.
Copper is well-known to migrate by thermal diffusion rapidly by when in
contact with other metals and heated. Rossi probably now realizes this.
Rossi’s old reactors were made largely of copper alloy.
Any copper found would of necessity have to be radioactive, if from
transmutation – and since it was not radioactive, nor in an anomalous
isotope distribution – then it had to be from migration instead.

Agreed. The issue of a “nearly complete lack” of
transmutation in many types of Ni-H is revealing.
Rossi has claimed this:
THE AMOUNT OF COPPER WE FIND AFTER 6 MONTHS OF OPERATION IS
OF ORDERS OF MAGNITUDE MORE THAT THE IMPURITIES IN THE 99.9999 Ni WE USE.

This is from an article by Matts Lewans:
Analyses of the nickel powder used in Rossi’s energy
catalyzer show that a large amount of copper is formed. Sven Kullander
considers this to be evidence of a nuclear reaction. [2]
There are many other similar, suggestive statements out
there. I think it is hard to justify the conclusion that there is almost no
transmutation being seen in Rossi's device.
It the excess heat is a million times more than can be
accounted for by a tiny amount of transmutation, then the explanation leans
one way.
This is a finding from (probably low-gain) PdD research.
There is little to conclude about NiH, as far as I can tell. Keep in mind
that in PdD d+d fusion may be more energetically favorable than
transmutation, by way of whatever magic is happening that is causing cold
fusion.
Transmutation does not happen without measureable levels of
radiation, such as would be seen on the meters of Bianchini, with his expert
qualifications.
This is a reasonable expectation, but I think the conclusion
is too pat. It is possible that a combination of enrichment on Rossi's part
and a natural mechanism that favors stable isotopes in LENR are sufficient
to keep the activity down if you do your prep work correctly.
Bottom line – the Rossi reaction is most likely a reaction
which fundamentally does not involve either high energy photons or
transmutation.
Sure -- everyone is entitled to his or her opinion, and we
grant you the same.
