You should add a subtag if transferring.
@François:
Would you please better explain the values for substation= and maybe add
some pictures.

We should surely not make an automatic conversion of the tag. Keeping
the old tag is useful for tracking substations that need reviewing.
Anyway, I (and not Francois) was the proposer of the substation proposal
and as such responsible for the substation=* key. The main issue at the
moment is whether we need a special value for the lowest level
substations, those directly supplying household consumers with low
voltage. I asked this question in another thread and got one suggestion:
"local_distribution". I have since tagged a few substations with
"minor_substation" as 'local' is a somewhat ambiguous term (I admit that
could also apply to 'minor) but I haven't documented anything so far.
For substations that are not for 'special purpose' (such as converter,
traction etc) the recommendation is to use the value 'transmission' for
substations having a highest operation voltage above 100 kV and
'distribution' for those below that voltage. There may be reasons to
deviate from this rule but the average mapper having no special
knowledge about a particular substation should stick to this rule.
