Just copy the SavedVariables folder from pc1 to pc2.

If the accounts are the same this will work. If not you need to change the @account names in the SavedVariables folders' .lua files manually after copying them.
There also exist addons to support this on the same PC, search for settings transfer oder settings in the addon search. But this does not work on all addons ads not all addons are created the same way and there exist like 5+ ways to store the savedvariables differently. If you are able to copy the settings from account 1 to account 2 this way you are able to copy the SV folder afterwards to pc2 and the 2nd account should register it then there (and the 1st account too).
