Aliases have been added for the changes, so these are not breaking changes:
Mismatched Copy commands have been renamed to match their corresponding Get command names (ie. Copy-DbaCentralManagementServer is now Copy-DbaCmsRegServer).
Most parameters named Password have been changed to SecurePassword. They’ve always been a
SecureStringdata type but this makes that clear.
The parameters ExcludeAllSystemDb and ExcludeAllUserDb have been changed to ExcludeSystem and ExcludeUser, respectively.
These are some of the non-breaking changes, but this latest release has several breaking changes too. Chrissy is promising no more breaking changes for a little while, so it’s probably a good time to upgrade and check those scripts to see what you need to change.
