GLYPH<SM590000> Another 512 GB VFM feature is purchased and installed concurrently. Now up to 512 GB can be added concurrently to LPAR B without reactivating the LPAR. 

Figure 2-2 shows the non-disruptive migration example.

## Disruptive migration 

An example of a disruptive migration includes the following features: 

GLYPH<SM590000> A z14 ZR1 CPC has two VFM features installed (512 GB per feature), LICCC = 1.0 TB. 

GLYPH<SM590000> LPAR A has 512 GB TB assigned, max = 1.0 TB. 

GLYPH<SM590000> LPAR B has 256 GB assigned, max = 1.0 TB. 

GLYPH<SM590000> LPAR A must be altered to have up to 1.5 TB. This change falls outside the range of maximum installed VFM. 

GLYPH<SM590000> Two extra 512 GB VFM features are purchased and activated concurrently (assuming plan ahead memory was ordered and memory is available). LPAR A must be reactivated with the new maximum VFM value of at least 1.5 TB and less than or equal to 2.0 TB. 

Figure 2-3 shows the disruptive migration example.
