Migrate cw20-base instances (if any), to new code id. This requires that the migrate_admin for these instances is set. Then, this requires access to the migrate admin account / credentials. This migration has to be done manually (using tgrade tx wasm migrate).
Update the tfi-factory contract config, trough an update_config message, to set the new code id of the cw20-base contract.
If frontend code (tgrade-app) still has the cw20-base code_id hardcoded, that has to be changed / updated to the new cw20-base code_id as well. @abefernan for reference.
Steps are:
tgrade tx wasm migrate
).tfi-factory
contract config, trough anupdate_config
message, to set the new code id of the cw20-base contract.
