after that, upgrade to nebula 3.0 with old password but it failed.

> ./nebula-console -addr=192.168.8.5  --port=1356 --u=root --p=nebula
2022/03/02 15:39:13 Fail to create a new session from connection pool, fail to authenticate, error: Invalid password
panic: Fail to create a new session from connection pool, fail to authenticate, error: Invalid password

using the modified password is fine

./nebula-console -addr=192.168.8.5  --port=1356 --u=root --p=nebula12
