The journaled files would have to be /restored/; any other method of /copy/ would not enable JID equivalence between the original database file [member] and the /copy/. The restore of the files could be made to a different *SYSBAS or a different Independent Auxiliary Storage Pool (iASP) than whence they were saved; whether that is to a physically different system or logically different partition is inconsequential.

The means of the journal (*JRN) getting there is not restricted to restore, nor the means of the journal entries [getting deposited] in the journal receivers. There is at least Remote Journal support, beyond just save and restore of the journal receivers, for which there is no requirement to save\restore the receivers.

A consideration would be to choose the correct starting sequence
number for STRJRNPF for the files once the library has been moved to
other LPAR before using APYJRNCHG.

Not sure of the mention of Start Journaling Physical File (STRJRNPF), but the first Apply Journaled Changes (APYJRNCHG) would typically specify the Last Save (*LASTSAVE) special value. If restoring the Journal Receiver (*JRNRCV) objects, then IIRC the APYJRNCHG request would be coded to specify the [set of the] journal receivers on the Receiver Range (RCVRNG) parameter, such that the From Entry Large (FROMENTLRG) specification for the starting Journal Sequence Number would identified as the special value *FIRST; in that manner, there is no need to know a specific Sequence Number.
