Upgrade Scripts:
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.
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)
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)

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
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).
