I had the same problem, but I need to replace the Break section "^ b" with the page break "^ m". Find and replaxce does not work for me. I decided to use this VBA script:
Sub ReplaceSectionBreaks() 'reliably replace section breaks with page breaks 'even if they're followed by tables Dim rg As Range Set rg = ActiveDocument.Range With rg.Find .Text = "^b" .Wrap = wdFindStop While .Execute rg.Delete rg.InsertBreak Type:=wdPageBreak rg.Collapse wdCollapseEnd Wend End With End Sub
try changing "^ b" to your "$$$ newpage" template, it should work for you too.
