Yes. The banknotes of the first series of banknotes and the Europa series will circulate in parallel. The date when the first series of euro banknotes ceases to be legal tender (i.e. the date from which they can no longer be used as a means of payment) will be announced well in advance. Even after this date, the banknotes of the first series will retain their value, as they can be exchanged for an unlimited period of time at the Eurosystem national central banks, including the Banco de Portugal.
