Wait @p{brk} until it has completely shut down (which might take a few minutes for older @p{brk} versions), then run the installer (on Windows) or just copy over @p{brk} /Applications/Bitcoin-Qt (on Mac) or bitcoind/bitcoin-qt (on Linux). @p{par} If you are upgrading from version 0.7.2 or earlier, the first time you @p{brk} run 0.8.1 your blockchain files will be re-indexed, which will take @p{brk} anywhere from 30 minutes to several hours, depending on the speed of @p{brk} your machine. @p{brk}
