|
||||
./migrate2rocky.sh -r
|

|
||||
# Migrate with internal mirror repository

### Known Issues
|
||||
|
||||
#### Custom replacements of default repositories
|
||||
@ -74,15 +88,6 @@ you can use the following script to recreate the package default alternatives:
|
||||
rpm -qa --scripts java-{1.8.0,11}-openjdk-{headless,devel} | sed -n '/postinstall/, /exit/{ /postinstall/! { /exit/ ! p} }' | sh
|
||||
```
|
||||
|
||||
#### IPA fails to start after migration
|
||||
|
||||
This issue is caused by a version mismatch due to the way that modules work that
|
||||
trick ipa into thinking that the package was downgraded even if it was not. To
|
||||
fix this issue run the following command after migration:
|
||||
```
|
||||
ipa-server-upgrade --skip-version-check
|
||||
```
