Transfer simbols for other local base

I created some general symbols derived from others (mainly Archimate). But when I restore the base on another computer, I can't see these symbols that are inserted in the model. I have already created a filter with the model associated with the symbols on the original computer and exported this filter to the other computer. But we verified in Administration > Method > Symbols that these symbols do not appear in the symbol base.
Who can help me how can I export/import or copy this simbols into new computer
