PROMPT Installation Summary:
PROMPT - Package: CT_MRDS.FILE_ARCHIVER
PROMPT - Version: 2.0.0 -> 3.0.0 (MAJOR)
PROMPT - New Strategies: CURRENT_MONTH_ONLY, MINIMUM_AGE_MONTHS, HYBRID
PROMPT - Backward Compatible: THRESHOLD_BASED (default)
PROMPT
PROMPT Next Steps:
PROMPT 1. Configure archival strategies per source:
PROMPT    UPDATE A_SOURCE_FILE_CONFIG SET ARCHIVAL_STRATEGY = 'CURRENT_MONTH_ONLY' WHERE A_SOURCE_KEY = 'LM';
PROMPT    UPDATE A_SOURCE_FILE_CONFIG SET ARCHIVAL_STRATEGY = 'MINIMUM_AGE_MONTHS', MINIMUM_AGE_MONTHS = 6 WHERE A_SOURCE_KEY = 'CSDB';
PROMPT 2. Test strategies using test_archival_strategies.sql
PROMPT 3. Monitor first archival run
