This question already has an answer here:
I'm using MultiBit version 0.5.16 (is this classic?) I am trying to get my bitcoins from Multibit to Electrum, but my transaction doesnt get confirmed. The current transaction is 1mBTC to test it first, so it's not a huge deal if I lose this 1mBTC. I saw here something similar: Transactions seen by peers, but not confirming The answer there is that the version is too old.
As MultiBit is no longer supported, is it even possible to update safely, to make sure my transaction will be confirmed?
Thanks in advance,
