|
## Updating: Blockchain Conversion
|
||
|
|
|
||
|
|
It is highly recommended that you delete the contents of your Monero working directory and sync from scratch. This directory can be found in ```~/.bitmonero``` on Linux and OS X, and on Windows in ```\Users\username\AppData\Roaming\bitmonero``` or ```\ProgramData\bitmonero```.
|
||
|
|
|
||
|
|
Syncing from scratch is EXTREMELY fast in this version, pretty much at bittorrent speeds, and will leave you with a fully verified blockchain.
|
||
|
|
|
||
|
|
*Alternatively*: if you want to grab the bootstrap (NOTE: there is a new bootstrap format!) off the website then you can get it at https://downloads.getmonero.org/blockchain.raw - once downloaded you can import it with ```blockchain_import --input-file /path/to/your/download.raw```. If you're particularly brave you can pass the ```--verify 0``` flag to skip verification during import.
|
||
|
|
|
||
|
|
*If you REALLY want to convert your old blockchain*: you can either use the ```blockchain_converter``` tool, or you can use ```blockchain_export``` to create a blockchain.raw, followed by ```blockchain_import``` to import it into the new LMDB format.
