Angela roses are best moved when dormant, so February would be ok. You can prune just before moving them, they'll be easier to handle and will start putting out new roots as the weather begins to warm. As for blackspot, a well fed and watered rose is stronger and will be better able to resist infection. So when replanting add a good handful of bonemeal to the planting hole plus well rotted manure, sprinkle some rootgrow over the roots, water in well and keep them well watered in the first few months. If after all that they show signs of blackspot, spray with Rose clear and keep hygiene around the rose good. Good airflow is important as well along with spraying the ground around the rose, which is where the spores will linger. Blackspot has been almost rampant this year due to the weather so even normally resistant roses have succumbed.
