Known Issues

Pool upgrade should be performed simultaneously for all nodes due to txn format changes.
All indy-cli pools should be recreated with actual genesis files.
Added and promoted nodes should be restarted (`systemctl restart indy-node`) after adding/promoting.

List of breaking changes for migration from indy-node 1.3 to 1.4:
https://github.com/hyperledger/indy-node/blob/master/docs/1.3_to_1.4_migration_guide.md

IndyNode 1.4 and LibIndy 1.5 compatibility:

General

By default LibIndy 1.5 will be compatible with IndyNode 1.3 (current stable), and not 1.4 (the new one).
LibIndy 1.5 can become compatible with IndyNode 1.4 if `indy_set_protocol_version(2)` is called during app initialization.

Guideline for teams and apps

Applications can freely update to LibIndy 1.5 and still use stable Node 1.3
If an app wants to work with the latest master or Stable Node 1.4, then they need to
support breaking changes (there are not so many, mostly a new reply for write txns as txn format is changed, see 1.3_to_1.4_migration_guide.md)
call `indy_set_protocol_version(2)` during app initialization

CLI Upgrading:

Old CLI (`indy`):

• upgrade from 1.3 to 1.4 version
• delete `~.ind-cli/networks/<network_name>/data` folder
• replace both old genesis files by new ones (from 1.4 node or from sovrin repo)

New CLI (`indy-cli`):

• upgrade from 1.4 to 1.5 version
• recreate indy-cli pool using 1.4 pool genesis file (from 1.4 node or from sovrin repo)

Use https://github.com/hyperledger/indy-sdk/blob/b4a2bb82087e2eafe5e55bddb20a3069e5fb7d0b/cli/README.md#old-python-based-cli-migration to export dids from your old CLI wallet to the new one (new indy-cli).
