LIGHTNING-DOWNGRADE(8) LIGHTNING-DOWNGRADE(8) NAME lightning-downgrade -- Tool to revert core lightning to an older version SYNOPSIS lightning-downgrade [ARGUMENTS]... DESCRIPTION lightning-downgrade reverts an upgrade by modifying the lightningd database back the prior version. lightningd must not be running at the time. A downgrade may not be possible if a new feature has been used that would be incompatible with an older version. In this case the downgrade will fail with a message and nothing will be changed. Use the latest lightning-downgrade to downgrade. For example, the v25.12 lightning-downgrade won't know how to downgrade v26.06. All minor versions are compatible, so a downgrade to v25.09 will work fine with v25.09.1 or v25.09.2, etc. VERSIONS * v25.12: downgrades to v25.09. Downgrade is not possible if withhold true has been used with fundchan- nel_complete, or if askrene-bias-node has been used. * v25.09: downgrade is not supported. OPTIONS * --lightning-dir=DIR Set the directory for the lightning daemon we're talking to; defaults to $HOME/.lightning. * --conf=PATH Sets configuration file (default: lightning-dir/config ). * --network=network * --mainnet * --testnet * --testnet4 * --signet * --regtest Sets network explicitly. * --rpc-file=FILE Named pipe to use to talk to lightning daemon: default is lightning-rpc in the lightning directory. * wallet=DSN Identify the location of the wallet. See lightningd-config(5) for de- tails. * --help/-h Pretty-print summary of options to standard output and exit. The format can be changed using -F, -R, -J, -H etc. * --version/-V Print version number to standard output and exit. BUGS You should report bugs on our github issues page, and maybe submit a fix to gain our eternal gratitude!
