Methods, computer program products, and systems are presented. The methods include, for instance: input data from the source environment, including application hosting data of each server in the source environment and one or more cloud type of the source environment. Candidate cloud types for target platform are listed and servers of the source environment are screened for eligibility for the migration. The target platform is selected by applying preconfigured selection rules on the application hosting data of each eligible server in the source environment. Migration recommendations for each eligible server in the source environment, including selected cloud type corresponding to the target platform, are produced.

A hijack avoidance technique avoids presenting an access to more than one of a chain of authentication objects, such as a chain of Lightweight Directory Access Protocol (LDAP) authenticators. A pre-filter determines whether an authentication object should be presented with the access by comparing either all or a portion of a domain suffix, an IP address, or other identification other than the user ID with predetermined values. If the filter criterion is met, the associated authentication object accepts or rejects the access. Otherwise, the access is passed to the next authentication object in the chain. The first authentication object may be associated with a hosting entity and successive authentication objects each associated with different customers of the hosting entity. By virtue of the filtering, each authentication object is presented only with a particular subset of all of the possible access identifiers, which avoids presenting all of the previously unauthenticated accesses to each authentication object in the chain.
