# Upgrade from 1.8.3 to 2.0

## micro service definition 1.Migrate config from “service_description” to “servicecomb.service”, for example:

1.8 ```yaml service_description:

name: Server hostname: 10.244.1.3

``` 2.0, ```yaml servicecomb:

service:

name: Server hostname: 10.244.1.3

```

2. change “instance_properties” to “instanceProperties”, for example:

1.8 ```yaml service_description:

name: Server instance_properties:

nodeIP: 192.168.0.111

``` 2.0 ```yaml servicecomb:

service:

name: Server instanceProperties:

nodeIP: 192.168.0.111

```

## change cse:// to http://

for example:

1.8 `go arg, _ := rest.NewRequest("GET", "cse://Server/instances", nil) ` 2.0 `go arg, _ := rest.NewRequest("GET", "http://Server/instances", nil) `

```

## others

1.if you use archaius.Getxxx(“cse.xxxx”) to pull config of go chassis

in this case, if you hacked go chassis config to do something, you must change as below

1.8 `go archaius.Getxxx("cse.xxxx") ` 2.0 `go archaius.Getxxx("servicecomb.xxxx") `

2.from 1.x to 2.0 there could be many of internal APIs has been refactored, but most API your code won’t call. if you find any problem, please record your problem in [issues](https://github.com/go-chassis/go-chassis/issues). or even help us to complete this instruction.

# Upgrade from 2.0.0 to 2.0.1 ## refactor log tool

you must change import

<=2.0.0 `go github.com/go-mesh/openlogging ` >=2.0.1 `go github.com/go-chassis/openlog `

please also simplify func name end with f to simple func name and use fmt.Sprintf

<=2.0.0 `go openlogging.GetLogger().Debugf("init %s's handler map", chainType) ` >=2.0.1 `go openlog.Debug(fmt.Sprintf("init %s's handler map", chainType)) `
